There was no immediate word on the extent of the injury. It's unknown when Victorino got hurt. He landed awkwardly on a diving attempt trying to avoid a collision with right fielder Ben Francisco on a ball hit by Carlos Lee in the fourth inning.
Victorino stayed in the game and hit a two-run single in the bottom half, but was removed for a pinch-hitter in the fifth.
The Phillies already are missing second baseman Chase Utley, outfielder Domonic Brown and closer Brad Lidge.
