Weiss was accompanied to the hospital by head athletic trainer Keith Dugger. There has been no timetable set for his return to the dugout.
Weiss, 51, began feeling ill after Tuesday night's game, a club spokesman said. He went to a hospital to be checked out before returning to the team hotel. Weiss was in the Rockies clubhouse earlier Wednesday before going back to the hospital, where he had the surgery.
