Herrin was removed from Wednesday's game against the Twins after getting hit on the elbow by a comebacker, Tim Stebbins of MLB.com reports.
Herrin was replaced on the mound immediately after taking an 89.4-mph line drive off his left (throwing) elbow in the sixth inning. He'll likely be sent in for X-rays to determine whether he suffered a fracture, and an update on his status should come in the near future.
