Carlos Gonzalez is scheduled to undergo an MRI on his right wrist Monday. CarGo returned to the lineup Friday following a four-game absence, but the wrist was still bothering him during the game and he sat out Saturday. He originally was hurt when he jammed the wrist while crashing into the outfield wall. It's a potentially season-changing injury for the Rockies, as they can't afford to be without one of their stars for a significant period of time given that they're already 7.5 games out of first place.
