United States men's national team manager Jurgen Klinsmann adds Joe Corona, Brad Davis, Jose Torres and Clarence Goodson to the roster ahead of USA's World Cup qualifying match against Mexico.

Jozy Altidore, Geoff Cameron and Matt Besler also suspended after getting yellow cards in Friday night's 3-1 loss at Costa Rica. And Michael Bradley appears likely to miss the Mexico match on Tuesday after spraining his left ankle.

''We're going to have to have guys step up, there's no question,'' US coach Jurgen Klinsmann said. ''I think we've talked about it over the last three years: We build toward this every game, so a guy can step in and not miss a beat and get the cohesion right.''

Originally in the starting lineup, Bradley limped off the field during warmups after spraining his left ankle and was on crutches at the bench during the game. He was replaced by Cameron.

''Michael might be our most important player,'' Donovan said.

Klinsmann said Bradley's ankle swelled and he will be sent for an MRI after the team arrives in Columbus on Saturday. Klinsmann may call in additional players for the match.

''I don't think it changes a lot,'' Klinsmann said. ''We need to have our four points at least to qualify. We will get those four points.''
