The Chicago Bears fear the knee injury sustained by versatile running back Tarik Cohen on Sunday is a serious one.

Coach Matt Nagy said following Sunday’s 30-26 win over the Atlanta Falcons that the team believes Cohen sustained a torn ACL in his right knee.

“It looks like he did end up tearing his ACL,” Nagy said. “That’ll be a big blow to us.”

Cohen will undergo an MRI to reveal the severity of the injury.

Cohen had two rushes for 21 yards and three catches for 20 before getting injured on a punt in the fourth quarter. He called for a fair catch, but Atlanta’s Brian Hill fell into his right leg.

Cohen was unable to put any weight on his leg as he left the field.

The injury comes one week after Cohen signed a three-year, $17.3 million contract extension through the 2023 season.

Cohen, 25, is in the final year of a rookie contract he signed after the Bears took him in the fourth round of the 2017 draft from North Carolina A&T.

Playing in every game through his first three seasons, Cohen racked up 1,027 yards rushing, 1,534 yards receiving and 14 total touchdowns. The 2018 first-team All-Pro also returned 95 punts and 30 kickoffs and threw two touchdown passes over that span.
