Former Florida safety Jaylen Watkins will miss the 2018 season, the Los Angeles Chargers announced on Sunday, after Saturday’s preseason game against the Seattle Seahawks. The early test results indicated a torn ACL, per the NFL Network’s Ian Rapoport.

Watkins was entering his fifth season in the NFL, his first season with the Chargers.

Watkins appeared in 48 games during his Florida career as both a cornerback and safety, finishing with 133 career tackles and three interceptions. His best career game at Florida came in his senior year during the 2013 matchup at Commonwealth Stadium against Kentucky, where Watkins racked up 10 tackles in a 24-7 win over the Wildcats. His senior year did not end well however, as the Gators finished with a 4-8 record after a 4-1 start under head coach Will Muschamp. Watkins was drafted in the fourth round of the 2014 draft by the Philadelphia Eagles.

Watkins, who is the older brother of Chiefs’ wide receiver Sammy Watkins, has played on the Eagles and Bills before landing in Los Angeles. He has 56 career tackles thus far in his NFL career, and a Super Bowl ring from his second stint with the Eagles last season.

After Watkins was ruled out for the season, the Chargers will bring in safety Micah Hanneman off the waiver claim to fill Watkins’ void.
