Royals' Raul Mondesi: Leaves game after collision at first base

Mondesi was removed from Friday's game after an apparent injury following a collision at first base, Pete Grathoff of the Kansas City Star reports.

It's unclear exactly what the injury was, but Mondesi was down for "a few minutes" before leaving the field under his own power. He appeared to take a forearm to the face, so a concussion can't be ruled out. Mondesi is part of a four-way competition for Kansas City's second base job, so any extended absence would be a major blow to his chances of breaking camp with the big club.
