Former Tennessee DL Derek Barnett won a Super Bowl ring as a rookie with the Philadelphia Eagles last season.

However, the 2017 first-round pick’s 2018 campaign hasn’t been going as smoothly. And now, per a report from ESPN’s Adam Schefter, he’ll miss the rest of the season.

Per Schefter’s tweet, Barnett is undergoing shoulder surgery, which will keep him out of the team’s nine remaining regular-season games and any potential playoff action:

Barnett recovered a Tom Brady fumble late in last year’s Super Bowl, helping to seal the victory for the Eagles.

He’ll be missed along the defensive line, especially with how much the Eagles have struggled in their quest to repeat as Super Bowl champs.
