Washington Commanders linebacker Leo Chenal, who was carted off the field Sunday, will undergo season-ending neck surgery, sources confirmed to NFL Network's Ian Rapoport.
Chenal suffered the injury in the second quarter of Washington's 33-31 upset victory over the Seattle Seahawks. The fifth-year veteran appeared to lead with his head while tackling Seattle's Emanuel Wilson and immediately went to the ground as medical personnel were quick to run to his side.
The crowd at Northwest Stadium chanted "Leo! Leo!" as Commanders teammates surrounded Chenal, who was taken off on a cart, raising his left hand as he approached the tunnel.
The Fox broadcast reported later Sunday that Chenal had feeling in all extremities and was taken to a hospital as a precaution.
NFL reporter Jordan Schultz first reported on Chenal's season-ending surgery Monday.
Chenal was starting Sunday in place of the injured Frankie Luvu, who was missing his second consecutive game with a groin injury.
The Commanders were thin at the position because another inside linebacker, Jordan Magee, was placed on injured reserve after the opener with a hamstring injury.
