Cardinals pitcher Adam Wainwright was forced to leave Saturday's game against the Brewers after stumbling out of the batter's box and needing assistance to get off the field, according to MLB.com. Wainwright suffered a left ankle injury and will be re-evaluated when the team returns to St. Louis, the team announced.

Wainwright allowed three hits in four scoreless innings in the game and added four strikeouts to his totals.

"What I've been told is don't even think anything until the doctor tells you what it is," he said to MLB.com. "I've not gotten my hopes up or down. I'm just going to try to be a positive influence here today and tomorrow and see what happens. … Everything right now is just speculation."

Wainwright did not have significant swelling even though his ankle was in a walking boot.

"I thought I got hit by something," said Wainwright, who confirmed it was the back of his ankle. "If you look at the replay, I get out of the box and I looked back to think the catcher's mask must of hit me or the bat must've hit me, something must've hit me."
