Athletics pitcher Jesse Chavez has been scratched from his scheduled start Wednesday, Jane Lee of MLB.com reports.
Chavez told reporters that he's dealing with rib soreness and has been having trouble breathing. An X-ray revealed no serious damage, and the team is considering sending him home to undergo an MRI. With only a few weeks remaining in the season, Chavez indicated that he may not pitch again in 2015. Oakland is yet to announce who will take the hill in Chavez's place Wednesday.
