Red Sox right-hander Clay Buchholz experienced erosion of his esophagus, and the condition caused internal bleeding.
The Red Sox say Buchholz has been evaluated at Massachusetts General Hospital, where he remained Tuesday night as Boston hosted the Toronto Blue Jays. The team says he is doing well and is expected to make a complete recovery.
Buchholz was placed on the 15-day disabled list Sunday with what the team described as a stomach illness. The Red Sox announced in a release Tuesday that he has esophagitis, which led to the erosion of his esophagus and an associated gastrointestinal bleeding.
