Ramirez remained on the ground for several minutes and was looked at by team trainers Tony Leo and Dave Pruemer. Bench coach Terry Steinbach and first-base coach Scott Ullger also came out to look at Ramirez, as Gardenhire had been ejected for arguing with second-base umpire Joe West in the third inning. Ramirez was able to walk off the field on his own but left clutching his jaw.
"It looked like he got knocked out, but he came in here and it looks like he has a little bit of a sore jaw," Gardenhire said.
Willingham said he did not call for the ball because he was camped under it and was surprised by the play, adding that he was happy to hear that Ramirez was feeling better after the game.
"I was worried about him," Willingham said. "But I was talking to him the whole time, so I knew he was fine. After we collided, the first thing I looked for was the ball, so I was happy to see it was in his glove."
Aaron Hicks took over in center field in the top of the seventh inning and grounded out to second base in the ninth inning of Minnesota's eventual 3-2 win.
