The Boston Herald reports: The week collapsed before Mike Sweetney could start his comeback. After spending roughly 1 years away from basketball, the veteran power forward signed on with the Celtics for a stint in this week’s summer league in Orlando, Fla. But Sweetney pulled a hamstring 15 minutes into his first game Monday, and spent the rest of his week getting treatment. Not surprisingly, Sweetney responded with gracious relief when Celtics assistant Clifford Ray walked over and told him there was a chance he could work out at the C’s practice facility next week… Sweetney now is listed at 275 pounds, though that may be an old number. He said he’s lost 40 pounds, though he’s not letting on to his actual weight.
