Los Angeles Galaxy and USA striker Edson Buddle is on trial at Birmingham City, reports BBC Sport. Blues have scored just 17 goals in 17 league games and boss Alex McLeish has made a new striker his top priority during the January transfer window.
"He's been training with us this week and he's done ok, but we're not at a stage yet where we're going to make any commitment," McLeish told BBC WM.
Buddle appeared twice as a substitute at the World Cup in South Africa.
The 29-year-old came off the bench in the 1-1 draw against England and the 1-0 victory over Algeria, both of which came in the group stages.
He plays his club football alongside former England captain David Beckham and scored 19 goals in 28 matches last season, in which the Galaxy reached the Western Conference final in the MLS before losing to FC Dallas.
