Sammy Watkins has undergone surgery in an area near his hip.

Watkins had the procedure done sometime before the Super Bowl for the injury that was suffered in a Week 13 win over the Cleveland Browns, according to sources.

It's unclear if the procedure will affect Watkins' availability for voluntary offseason workouts, which begin April 6.

Watkins led the Buffalo Bills in targets (128), yards (982) and receiving touchdowns (six).
