[AMERICANS ABROAD] Only 24 hours after U.S. coach Bob Bradley revealed the 30 players he will choose from to pick his squad for the World Cup, he got his first injury scare when forward Eddie Johnson came off with a possible hamstring injury in the first half of his Greek club Aris' match against AEK Athens -- what is for Aris a meaningless playoff game.

Initial reports were that the injury is not serious.

Johnson had helped his cause for a berth on the 30-man preliminary World Cup roster -- if not the final 23-man roster -- with three goals in the first three games of the competition, a four-team tournament to determine Greece's second entrant in next season's UEFA Champions League.

The other three playoff teams move into the Europa League. Placement in second to fourth place only determines the round the team enters next year's Europa League.

But as the bottom-ranked of the four teams in the competition, Aris began four points behind leader PAOK and was mathematically eliminated on Wednesday.

Leonardo scored for AEK (6 points) in injury time to give it a 1-1 tie with Aris (4). PAOK (13) extended it lead to six points at the top with a 1-0 win over Olympiakos (7).

Fellow American Freddy Adu played the first 75 minutes for Aris, which has two more games to play on Sunday and Wednesday.
