Jose Reyes led off the fifth inning by grounding a ball towards first base. As Reyes, Albert Pujols and Lohse all converged on nearly the same spot, Lohse attempted to slow down, and made an awkward turn on his knee. He pitched the rest of the fifth inning but was removed for the sixth.
"I tried to stop, and it just wasn't very normal to try to stop like that," Lohse said. "I saw the ball going back behind me, and I tried to stop. As soon as I went to bend down, it was pretty painful."
Manager Tony La Russa said that Lohse was not removed because of the injury. Still, the condition was somewhat concerning, as Lohse was still feeling discomfort after the game.
"It's still a little sore," he said. "But I've been icing off and on, so it's pretty numb right now. It feels pretty numb from the ice. There's still a little swelling, but I can't say much about it right now."
