Team spokesman Josh Rawitch said that the 24-year-old Billingsley slipped on ice outside his house in Reading, Pa., and suffered a spiral fracture of the fibula in his left leg on Friday.

He had surgery to put a plate in and will be in a cast for two weeks. Rawitch said the surgery went as expected and Billingsley should be ready to throw by spring training.

Rawitch said the surgery was performed by Dr. Paul Neuman, an orthopedic surgeon in Reading, after consulting with team surgeon Dr. Neal ElAttrache.

Billingsley was 16-10 with a 3.14 ERA this past season. He lost Game 2 and Game 5 of the National League championship series against the Philadelphia Phillies.
