from the above posted link:
Mussina left New York's 8-5 win over Boston on Sunday night after four innings because of tightness in his groin.
The move is retroactive to Monday. Mussina, who has already matched his victory total from last season despite being winless in four starts since July 30, will be eligible to return on Sept. 5.
Mussina said he probably could pitch in a week if he was absolutely needed. He thought the Yankees' place in the AL East did factor in the decision.
"I think we would re-evaluate things if the standings were different," he said. "We're up 6 1/2 games. I'm sure that had some bearing."
If the Yanks maintain a steady 5 game lead the rest of the way, is there a chance that Moose won't pitch until late september? that would be fantasy baseball devastation....
