FORT MYERS, Fla. — Boston Red Sox pitcher Junichi Tazawa will have elbow ligament replacement surgery on his right elbow next week, an operation that is likely to sideline him for about a year.

Red Sox manager Terry Francona said Dr. James Andrews will operate on Tuesday in Birmingham, Ala.

Tazawa, a right-hander who turns 24 in June, signed with the Red Sox in December 2008. He was a combined 9-7 with a 2.55 ERA at three minor league levels last year and 2-3 with a 7.46 ERA in four starts and two relief appearances for Boston.
