Athletics starting pitcher Jesse Hahn was forced to leave Saturday's game with a blister on his right middle finger.
On Sunday, Hahn was wearing a bandage on the finger, but he was confident he wouldn't miss a start, per the Bay Area News Group.
There's still a possibility that the blister will keep him out of the April 23 start, however, so that the blister can heal fully. Jesse Chavez would get the start in his place, per MLB.com.
