The Tampa Bay Buccaneers fear linebacker Kwon Alexander suffered a torn ACL during Sunday's game against the Cleveland Browns, sources told NFL Network's Mike Garafolo and Ian Rapoport.
Alexander will undergo an MRI which will determine the severity of the injury.
The 24-year-old suffered the injury during the second quarter and didn't return.
Alexander was named to his first Pro Bowl in 2017 and has emerged as a vital component of the Buccaneers' defense.
Tampa Bay and Alexander were reportedly discussing a new contract prior to Sunday's game.
