Peavy MRI reveals bruise, swelling
The White Sox have no firm plan as to how to handle Peavy. For the short term, Peavy likely will be shut down until the swelling subsides.
Chicago's long-term view might dictate that the $61 million man sits out the final month of the season. The plan would be to work with pitching coach Don Cooper and the team's trainers toward debuting with the rotation in 2010.
Peavy is known as a workaholic who might balk at not pitching competitively the rest of the season.
