WASHINGTON -- White Sox pitching coach Don Cooper, who has been hospitalized since Tuesday with diverticulitis, will miss the rest of the team's road trip that continues in Cleveland this weekend and Toronto next week.
First-year bullpen coach Bobby Thigpen has assumed Cooper's duties and will continue to sit in the dugout. Organizational pitching coordinator Curt Hasler will join the club to help Mark Salas supervise the Sox bullpen.
Cooper was taken to Inova Hospital in northern Virginia on Tuesday morning, after the team had arrived here on Monday. When he's released he'll go to his home in Nashville to continue his recovery.
Diverticulitis is a common digestive disease which involves the formation of pouches within the bowel wall, typically occuring within the large intestine, or colon. It can be very painful.
