Cavalli experienced shoulder discomfort when throwing Wednesday and will be shut down from throwing for 3-7 days as a precaution, Jessica Camerato of MLB.com reports.
He resumed a throwing program Wednesday and quickly re-aggravated his shoulder injury, after which Cavalli received a cortisone shot, per Mark Zuckerman of MASN Sports. The right-hander won't return to game action this season, but he will compete for a rotation spot next year in spring training if he is healthy.
