Tejada bunted for his third hit of the game and appeared to slow down slightly while running toward first base. He went into a headfirst slide and was safe but lay on the ground atop first base in pain as a team trainer rushed out. After a brief examination, Tejada was removed from the game and replaced by pinch-runner Cesar Izturis.
Baltimore manager Dave Trembley said he was uncertain of Tejada's condition after the game but the veteran infielder told reporters he suffered a groin strain that isn't likely to keep him out very long.
Tejada had also singled in the first and fourth innings. All three hits came off Oakland starter Justin Duchscherer.
