BATON ROUGE, La. — LSU will lose freshman pitcher Eric Walker for the entire 2018 season.

The university says Walker needs Tommy John surgery and on Wednesday will undergo the procedure to fix a tear in the ulnar collateral ligament of his right elbow near his Arlington, Texas home. It will be performed by Dr. Keith Meister, the head physician of the Texas Rangers.

The typical recovery time for Tommy John surgery is 12 to 16 months.

Coach Paul Mainieri says Walker was “a rock all year” and a “vital contributor.”

Walker earned several Freshman All-American honors this season after going 8-2 with a 3.48 ERA.

He is the second LSU pitcher this season to require the surgery. Reliever Doug Norman had his operation in March after tearing his ulnar collateral ligament Feb. 26.
