Bengals right tackle La'el Collins out for the season with torn ACL and MCL
Collins, 29, was enjoying a strong first season with the Bengals after spending his first six years with the Dallas Cowboys.
He started all 15 games up to this point after being brought in to stabilise Joe Burrow's protection, and it has been the first of Burrow's three seasons where he has averaged fewer than three sacks per game.
The Bengals are currently one of the hottest teams in the NFL, riding a seven-game winning streak with nine victories from their past 10 outings, but the loss of Collins will undoubtedly be a massive blow.
According to Enquirer's Kelsey Conway, the team's initial on-field ACL exam appeared to indicate he had not suffered a tear, but an ensuing MRI produced much more dire results.
They finish their season with home games against the Buffalo Bills and the Baltimore Ravens, but with a playoff berth already secured, the priority will now be to reach the postseason as healthy as possible.
