SÃO PAULO — Jozy Altidore will miss the Americans’ World Cup game against Portugal on Sunday because of his strained left hamstring and appears likely to sit out next week’s match against Germany.

The U.S. probably needs to advance to the knockout phase if the forward is to return to the tournament.

Altidore was hurt in the 21st minute of Monday’s 2-1 win over Ghana, and the U.S. Soccer Federation said Thursday he will not play against the Portuguese.

“It’s bad news, but I think the team will handle this,” midfielder Jermaine Jones said. “We have to handle that.”

Aron Johannsson replaced Altidore for the second half against Ghana. Chris Wondolowski is the other striker who could join Clint Dempsey in the attack.

Dempsey, the Sounders FC star, has not decided whether he will wear a mask to protect his nose, which was broken during the Ghana game.

BRASILIA, Brazil — Starved of World Cup action for 16 years, Colombia — and its fanatical traveling supporters — are certainly making the most of being back on soccer’s biggest stage.

Driven on by a partisan pro-Colombian crowd that turned the Estadio Nacional into a sea of yellow, the South Americans scored through James Rodriguez and substitute Juan Quintero in a devastating six-minute spell in the second half to beat Ivory Coast 2-1 Thursday.

A second victory in Group C, after a 3-0 win over Greece, helped Colombia qualify for a place in the last 16. A 0-0 draw between Japan and Greece in the later group match ensured Colombia would progress to the knockout rounds.

“We have had two wins with players who are playing their first World Cup,” Colombia coach Jose Pekerman said. “We’re happy to have defeated such a good opponent. We have a lot of young players, and this is going to help them grow.”

NATAL, Brazil — Reduced to 10 men after captain Costas Katsouranis was sent off in the 38th minute with his second booking, Greece held on for a 0-0 draw with Japan that kept both alive in Group C.

Both teams inserted new strikers in search of goals and a first victory, but ultimately the main objective was survival and both achieved that with one match left in group play. Japan would have been eliminated with a loss.
