When Joe Burrow left Sunday’s game at Washington with an apparent left knee injury and then tweeted, “See ya next year,” before it ended, it became clear that the Cincinnati Bengals quarterback’s rookie season was likely over.

If the initial diagnosis is correct, then Burrow is certainly done for 2020.

NFL Network’s Ian Rapoport reported that Burrow has suffered a torn left ACL, per the early prognosis, and that there could also be “additional damage.” The former LSU quarterback will undergo an MRI to confirm the diagnosis and also to find out what other injuries he may have suffered.

It was only the 10th game of Burrow’s NFL career after he was selected by Cincinnati with the No. 1 overall pick in the 2020 NFL Draft. This season, he had passed for 2,688 yards, 13 touchdowns and five interceptions, while also rushing for three touchdowns, in what was shaping up to be a strong rookie campaign.

On Sunday, Burrow was 22-for-34 for 203 yards and a touchdown before he suffered the injury while getting hit by a pair of Washington defenders. Burrow was then carted off the field, receiving words of encouragement and support from both teams upon his exit.

Things may not have ended well for Burrow in 2020, but he impressed during his time leading the Bengals’ offense, which should give the franchise optimism for the future. It shouldn’t be a surprise, considering Burrow was coming off a Heisman Trophy-winning campaign at LSU in 2019, when he led the Tigers to a 15-0 season and a national championship.

So, while Burrow appears to be done for now, he could return in the future and pick up where he left off in his rookie season.
