Cincinnati Bengals quarterback Joe Burrow's season is reportedly over as the knee damage the quarterback suffered in a defeat to Washington Football Team was more serious than first feared.

Burrow was carted off the field after he was hit low while throwing a pass in the third quarter of a 20-9 loss at FedExField.

The NFL's number one draft pick underwent an MRI scan on Monday, which NFL Network Insider Ian Rapoport and NFL Network's Tom Pelissero say revealed he has torn his medial collateral ligament and anterior cruciate ligament.

Burrow is also said to have suffered further structural damage in his left knee and is facing a long absence.

The 23-year-old will reportedly undergo reconstructive surgery and rehabilitation ahead of the 2021 season.

Burrow was 22-of-34 passing for 203 yards, a touchdown and no interceptions before he made an early exit.

The 2-7 Bengals are expected to recruit a new QB, with Ryan Finley their only backup for the unfortunate Burrow.
