Peavy described a severe injury Wednesday, saying the muscle has apparently torn completely away from the bone. He could be gone for the season.
Peavy had to leave Tuesday night's game against the Angels in the second inning after delivering a pitch. A former Cy Young Award winner with the San Diego Padres, Peavy is 7-6 with a 4.63 ERA in 17 starts this season.
The White Sox have won 20 of their last 25 games to climb back into the AL Central race.
Oddsmakers from online sports book SBGGLOBAL.com currently list the White Sox as 20/1 long shots to win the 2010 World Series and 10/1 to win the American League Championship.
