Chicago White Sox starter Carlos Rodon had arthroscopic surgery on his left shoulder and could miss the beginning of next season, general manager Rick Hahn said.

Hahn said Thursday the left-hander should miss six to eight months after the surgery, which revealed significant bursitis, which was removed in Wednesday’s surgery.

Rodon, 24, missed nearly the first three months of the season with shoulder and biceps problems and went 2-5 with a 4.15 ERA in 12 starts before returning to the disabled list on Sept. 8.

"We’ll know more about the specifics of the timing when Carlos completes his rehab and begins throwing in spring training," Hahn said.

In three seasons, Rodon is 20-21 with a 3.95 ERA.
