White Sox reliever Danny Farquhar remained in stable but critical condition Sunday after surgery on Saturday at Rush University Medical Center.
Farquhar has been hospitalized since Friday, when he suffered a brain hemorrhage in the dugout caused by a ruptured aneurysm.
The Sox did not provide any news on Farquhar on Sunday, but a source told the Tribune that Farquhar underwent a medical procedure Saturday night to relieve swelling in the brain. Farquhar is under the care of Dr. Demetrius Lopes and the Rush neurosurgical team.
White Sox vice president Ken Williams confirmed the procedure on Sunday in an interview with USA Today.
