Report: White Sox Reliever Jones Had Elbow Surgery, '15 Season In Doubt

(CBS) The White Sox knew they were likely going to be without right-handed reliever and potential closer Nate Jones for the rest of this season. Now they face the possibility of not having him for all of 2015, too.

Jones underwent reconstructive elbow surgery on Tuesday after injuring it in his rehab attempt from the back surgery that had originally sidelined him, CSNChicago.com's Dan Hayes reported Wednesday afternoon. Famed surgeon Dr. James Andrews performed the operation after Jones tore his UCL, Hayes reported, citing White Sox general manager Rick Hahn.

The timetable is expected to be 12 or more months.

The White Sox bullpen has struggled mightily this season with the absence of Jones and Matt Lindstrom.  Jones originally had a hip inure, then it was revealed he had a back problem, for which he had surgery in May. He pitched in two games this season but didn't record an out.

In other injury news, White Sox outfielder Avisail Garcia (shoulder) and Lindstrom (ankle) will report to Triple-A Charlotte on Friday to begin rehab assignments, Hayes reported.
