GLENDALE, Ariz -- Dodgers outfielder Carl Crawford was removed for an unknown reason in the second inning of a Triple-A game against the Mariners on Tuesday at Camelback Ranch.

It's unclear if Crawford was injured in the game, but he was taken to the clubhouse on a cart. Sources indicate the outfielder might have tweaked his right shoulder.

The Dodgers will give an update on Crawford when manager Don Mattingly speaks to the media later Tuesday in Australia.

Crawford started in left field and struck out looking in his only at-bat of the game in the first inning of the Minor League game. He did not make the trip to Australia for Opening Day because he'll be placed on paternity leave.

The veteran missed time last month because of right quad and hamstring tightness, but he has played regularly. He spent a month on the disabled list last year with a strained left hamstring. Crawford played in only 31 games because of injuries in 2012.
