The Washington Commanders are awaiting additional news about the condition of defensive tackle Jonathan Allen, fearing he may require season-ending surgery for a pectoral injury, NFL Network reported Monday.

Allen sustained the injury in the Commanders’ 30-23 loss Sunday to the Baltimore Ravens and was ruled out of the game in the fourth quarter.

Per the report, he will get a second opinion before any decisions are made.

Allen, 29, would represent a significant loss for the surprising Commanders (4-2), who lead the NFC East.

A two-time Pro Bowl selection, the 6-foot-3, 300-pound Allen has manned the defensive line since Washington selected him in the first round (17th overall) of the 2017 NFL Draft.

He has avoided a major injury until now, starting at least 15 games in each season since 2018.

In 107 career games (all starts), he has 41 sacks to go with 397 tackles (59 for loss) and 117 quarterback hits. In six games this season, he has 15 tackles and two sacks while playing 62 percent of the snaps on defense.

The Commanders host the Carolina Panthers (1-5) in Week 7.
