DOUALA, Cameroon (AP) — The presidents of Cameroon and Ghana have called for investigations following disappointing World Cup showings that saw both countries eliminated during the group stage.

In Cameroon, state media said President Paul Biya had given his prime minister one month to submit a report on the Indomitable Lions' "inglorious campaign."

A statement from Biya's office said the report should include steps for a "profound and deep restructuring of Cameroonian football."

The state-owned Ghana Broadcasting Corporation said President John Mahama had also decided an investigation was needed. Mahama has already replaced his sports minister.

Both teams placed at the bottom of their groups and had their campaigns marred by disputes over appearance-fee payments. Two Cameroon players also scuffled during a match against Croatia, and the national football federation derided their "disgraceful behavior."

Brazil and Colombia win

RIO DE JANEIRO (AP) — Brazil has advanced to the quarterfinals of the World Cup with a 3-2 shootout win over Chile. Neymar scored the winner in the shootout after the match ended 1-1.

Up next for the host team in the quarterfinals will be Colombia, which eliminated Uruguay 2-0.

American forward Altidore trains on own again

SAO PAULO (AP) — Jozy Altidore has trained on his own again, an indication the injured forward isn't likely to start in the United States' second-round World Cup game against Belgium next week.

Altidore hasn't played since straining his left hamstring in the opener against Ghana on June 16. He joined teammates Saturday to applaud equipment manager Jesse Bignami for his birthday, then broke off to jog around the fields at the Sao Paulo Futebol Clube training complex with fitness coach Masa Sakihana as the rest of the Americans warmed up.

In the knockout stage of consecutive World Cups for the first time, the U.S. plays Belgium on Tuesday night in the northeastern city of Salvador.
