(CNN) -- Brazil and Portugal played out a disappointing draw as Group G reached its climax but both cruised into the last 16 of the World Cup.
Striker Nilmar came the closest to breaking the deadlock for Brazil, as his shot was diverted onto the crossbar by Portugal goalkeeper Eduardo.
Brazil finish as group winners and will face either Spain, Chile or Switzerland in the second round. Portugal go through as runners up and will face either Spain or Chile.
Ivory Coast comfortably beat North Korea 3-0 in the group's other match but it wasn't enough to give them hope of qualifying in place of Portugal.
Brazil 0-0 Portugal
During a cagey opening in Durban, neither side created any chances of note in the opening 20 minutes of the game, that was dominated by a series of niggly fouls.
Brazil defender Juan was lucky not to see a red card as he hand balled a long pass that would have released Cristiano Ronaldo.
The first real chance came on the half hour mark as Nilmar met striker Luis Fabiano's cross but Portugal goalkeeper Eduardo turned his effort onto the crossbar.
Fabiano then headed narrowly wide of the target as he met Maicon's cross from the right flank.
Ronaldo registered Portugal's first effort on target five minutes before the break but his powerful shot was easily gathered by Brazil goalkeeper Cesar.
A series of fouls disrupted the flow of the game, as the referee produced seven yellow cards before half-time arrived -- including one to Tiago for diving.
Fabiano forced Eduardo into another save with a looping header before Simao tested Cesar at the other end but his shot was right at the 'keeper.
A powerful run from Ronaldo created a chance for Raul Meireles but his flick towards goal brushed the side-netting via a touch from Cesar.
Substitute Ramires brought a superb save out of Eduardo near the end as his shot was deflected towards the top corner but both sides were content to hold out for a point.
Ivory Coast 3-0 North Korea
Ivory Coast knew they needed to rack up as many goals as possible against North Korea to have any chance of qualifying and they opened the scoring within 15 minutes.
Yaya Toure collected Arthur Boka's cross before stroking the ball into the far corner. Just a minute later, full-back Romaric hit the post.
In the 20th minute striker Didier Drogba smashed a shot against the crossbar before Romaric nodded the rebound into the net.
Gervinho nearly made it 3-0 seven minutes before half-time but his shot from an angle flicked off the outside of the post.
Drogba came close to adding a third after the break but his diving header flew over the crossbar before substitute Salomon Kalou smashed a shot over the bar from close range.
With ten minutes remaining Kalou met Boka's cross to fire into the net and despite having two goals disallowed for offside, the Ivory Coast couldn't add to their tally.

It is the latest in a series of global investigations aimed at the firm.
Google has admitted that its Street View cars "accidentally" collected data from unsecured wi-fi networks in 30 countries because of some rogue code in the software used by the service.
The US investigation will attempt to answer how that code ended up being used by Street View.
Google has explained that the data was gathered as it logged wi-fi hotspots to help it develop location-based services. It has since stopped collecting such data.
But it has never gone into details about how the software came to be included in the Street View system, saying just that it was the work of a "single engineer".
The US investigation aims to drill down into Google's working practices.
It will ask the search giant who inserted the code and why, whether the data was extracted and why Google saved it.
In a letter to the search giant, Connecticut's Attorney General Richard Blumenthal has asked for copies of the company's internal procedures regarding Street View and for exact details of how and when Google learned that its cars were capturing sensitive data.
The letter also asks why Google recorded the signal strength and quality of personal and business wireless networks.

Mr Blumenthal said he expected a "significant number of states to participate". 30 have so far signed up.
He described the accidental collection of data as a "deeply disturbing invasion of personal privacy".
"Street View cannot mean Complete View - invading home and business computer networks and vacuuming up personal information and communications.
"Consumers have a right and a need to know what personal information - which could include e-mails, web browsing and passwords - Google may have collected and why. Google must come clean," he said.
The French data protection agency CNIL has had an early view of some of the information collected and said it included data such as passwords.
It said it was considering whether to prosecute the firm.
Like many other data protection agencies it had requested Google hand over copies of the data it gathered to find out whether it breached privacy rules.
Investigations are also on-going in Germany, Spain, Italy, Australia, New Zealand and Canada.
Google said it was working with all the investigators and offering to delete all the sensitive data.
It has defended its position with Google boss Eric Schmidt saying there was "no harm, no foul" in collecting the snippets of information.
"Who was harmed? Name the person," Mr Schmidt said during an interview at the company's annual Zeitgeist conference held in Watford in mid-May.

It’s a pain in the backside to get permits for, and many places are still off limits to foreigners, but here are seven reasons why eastern Tibet should be firmly fastened to your Tibet itinerary.
1. Getting off the beaten track
Roads are improving out this way, but there are still long stretches of unmade dirt tracks that turn into mud baths as soon as it rains. Worst-case scenario: landslides. Best-case: an uncomfortably bumpy ride. But, hey, tarmac would be too easy, wouldn’t it?
2. Lush, green and gorgeous














If the vast, desert-like Tibetan-plateau landscape doesn’t rock your boat, head east to find sub-tropical Tibet: dripping-wet forests, raging rivers and towering gorges. This is the face you never knew Tibet had.
3. The coolest guesthouse in Tibet?
The picture says it all really. This dream-come-true guesthouse on the outskirts of Rawok has to be the coolest place to stay in all of Tibet. Not only do you get incredible views of Ngan-tso Lake and the surrounding snow-capped mountains but the rooms are cheap (about Y100 for a double, or Y50 for a bed in a dorm) and they all have wifi.
4. Tashigang Village












This simple farming village, a short walk from Lunang, is bursting with rustic charm and offers a rare chance to stay with a Tibetan family in a traditional Tibetan stone house. Six of the villagers here have turned their wonderful homes into family guesthouses and all offer cheap beds, home-cooked meals and even a hot shower! The surrounding countryside – fields of barley and rapeseed leading to pinewood forests – is perfect for hiking. If that’s too energetic for you, find a villager willing to rent you their horse for an hour or two, and trit-trot your way into the hills.
5. Hiking the Bonri kora











This fantastic holy hike (or kora), around Bonri, the Bon people’s most sacred mountain, used to take two or three days. But now a new road leads around the back of the mountain, so travellers and pilgrims alike can complete the most exhilarating section – up and over the Bonri pass – in around seven hours. It’s still a tough slog, up steep trails and at altitudes approaching 5000m, but it’s incredibly rewarding to follow pilgrims over such sacred ground through such fabulous scenery. Yaks graze on grasslands at the top, while the slopes lower down are covered in blankets of rhododendrons. Get your driver to drop you at Mirui Village, then just follow the prayer flags, or the pilgrims, up and over the mountain until the trail meets the main highway where, with a bit of luck, your driver will be waiting for you.
6. Camping around Draksum-tso










It may cost Y100 just to see it these days, but Draksum-tso is still the most picturesque lake in eastern Tibet. Chinese tour groups love this place, and who can blame them. But if you want to get away from the crowds, bring a tent and walk clockwise round the lake from Tsodzong Monastery island (where the bus drops you off) until you get to a fabulous camping spot known as Qiuzi Dong. It should take about three hours, leaving you with about a four-hour hike in the morning to complete your circuit of the lake.
7. Not another Westerner in sight









Eastern Tibet is the perfect place for mixing with the locals because, chances are, you won’t meet tourists of any kind for much of your time here. Those you do see will probably be Chinese, and they’re just as excited about being here as you.

New York (CNN) -- A flag that accompanied Lt. Col. George Armstrong Custer and his 7th Cavalry into their final battle 134 years ago will be put up for auction, the auction house that will handle the sale said Friday.

Custer led more than 200 other other soldiers into battle against thousands of Lakota and Northern Cheyenne warriors on June 25, 1876, at the Little Bighorn River in what is now Montana. None of the U.S. soldiers survived the battle.

The flag that will be sold in October is tattered and fragile, measures 27½ by 33 inches and may be stained with blood. It was found three days after the Battle of Little Bighorn -- or the Battle of Greasy Grass Creek, as the victors called it -- beneath the body of one of Custer's men killed in the battle.

Sgt. Ferdinand Culbertson, a member of the burial detail assigned to retrieve the remains of the 7th Cavalry, found the Cavalry guidon, or swallow-tail flag, that was used by cavalry companies. The design reduced wind drag as the soldiers advanced.

"It's not a piece of decoration," said Sotheby's vice chairman, David Redden. "It's a sacred relic. People died for this flag. This flag is really important as it symbolizes one of the great and mythological battles in American history."

Another flag from the battle site was found months later in an Indian village seized by U.S. troops and is now owned by the National Park Service, but Redden said it is in very poor condition.

Custer's last battle was part of the United States government's 1876-77 campaign to retake the Black Hills region, ceded in perpetuity by an 1868 treaty to the Lakota. But when gold was discovered in the area, the army was sent to push the aboriginal Americans to a reservation set up for them.

The 7th Cavalry surprised the Lakota and Cheyenne, camped on the river banks, but Custer vastly underestimated their number and was crushed.

Sitting Bull and Crazy Horse were among the Lakota leaders who took part in the battle.

The Detroit Institute for the Arts acquired the flag in 1895 for $54 but has decided to part with it and use the proceeds for future art acquisitions.

The Institute's director, Graham Beal, says the flag won't be missed as it was often on loan to other institutions, most recently at the Little Bighorn Battlefield National Monument in Montana.

"The sale will help with future acquisitions," said Beal. "With the proceeds we will get art for the collection. Even though we are in Detroit, we have one of the great universal collections including Baroque, African and early modern collections. We are right up there with Chicago, Cleveland and Philadelphia.

Author Nathaniel Philbrick, whose book "The Last Stand: Custer, Sitting Bull and the Battle of the Little Big Horn" was released in May, said the significance of shabby flag is enormous.

"It's not only symbolic, but it's also just a terrific artifact," he said. "It's pretty intact and given what it went through, it's amazing."

John Doerner, chief historian at the Little Bighorn Battlefield National Monument, said he believes the flag is stained with the blood of a fallen soldier and that the banner belongs to the American people.

"It was an act of courage and bravery," said Doerner, a 20-year veteran of the National Parks Service.

"To lose the colors was really something that a soldier would give their lives [to prevent]," he said.

Doerner is helping oversee events for the battle's anniversary this weekend at the national monument, where visitors will hear symposiums and view re-enactments. He is hopeful that a benefactor will purchase the flag and loan it to a national museum.

Redden said expectations are good that the Custer flag sale price might exceed Sotheby's $2 million to $5 million estimate, but the hope is that the sale will come close to the $12.3 million paid for a Revolutionary Battle flag in 2006, a record for any military relic at auction.
