Zimmermann said Thursday that the swelling in his jaw had gone down and that he didn't have a headache, and he planned on beginning his usual routine between starts. The right-hander's next scheduled start would be Tuesday against Baltimore.
Zimmermann sustained the bruise when he was struck by a line drive hit by Jason Kipnis, the second batter in the first inning. Zimmermann was down for several minutes before walking off the field. He passed the concussion protocol test and was taken for X-rays.
"He's ready to go, which is pretty amazing," manager Ron Gardenhire said. "He's a very lucky man."
Zimmermann had his jaw broken on a line drive while pitching in college in 2007, and doctors inserted 11 screws and several plates.
