White Sox reliever Danny Farquhar was in stable but critical condition Sunday, a day after undergoing surgery to relieve swelling on his brain after suffering a brain hemorrhage while in the dugout during a game.

White Sox vice president Ken Williams told USA Today Sports that Farquhar remained Sunday in the neurosurgical ICU unit at Rush University Medical Center in Chicago and was being closely monitored by neurosurgeons after undergoing a complicated procedure Saturday night.
