Here is the posting on the White Sox' Facebook page about today's surgery:
Paul Konerko underwent successful surgery this morning at Rush University Medical Center to remove a loose body from his left wrist.
The procedure was performed by Dr. Mark Cohen, White Sox hand and wrist specialist, with assistance from Dr. John Fernandez and Dr. Charles Bush-Joseph of Midwest Orthopedics at RUSH.
Konerko, 36, was released from the hospital and will return tomorrow to his offseason home in Scottsdale, Ariz. Sutures will be removed from his wrist in 7-10 days, and he then will undergo a follow up examination by a White Sox hand and wrist specialist in Glendale, Ariz. Konerko is expected to make a full recovery and be ready for the start of spring training.
No word on whether or not the "body" was Jimmy Hoffa.
