Posey was removed from Friday night's game against the Arizona Diamondbacks after taking a foul tip off his mask in the bottom of the second inning. He sat out Saturday's game.
Posey had to gather himself after the blow to his mask. He singled in the third inning and, upon reaching first base, was tended to by a trainer and first-base coach Jose Alguacil. Posey took off his helmet and walked to the dugout. Nick Hundley came on as a pinch runner.
The Diamondbacks went on to win 6-3.
