Cincinnati Bengals offensive tackle Trent Brown was carted off the field for Monday’s game against the Washington Commanders due to a right knee injury and was immediately ruled out.

Brown has spent two stints in New England, including the 2018 season when he served as the top blindside protector for legendary quarterback Tom Brady.

It was a somber moment on the field in Cincinnati as Brown remained on the ground, writhing in pain. The injury occurred when the veteran offensive tackle awkwardly sat on his leg while being pushed back by a defender.

Brown’s teammates surrounded him supportively as the cart came out and took him back to the locker room.

Brown was a huge success story as a seventh-round draft pick. He won a Super Bowl with the Patriots and was nominated for the Pro Bowl with the Oakland Raiders in 2019.

The Bengals are now holding their breath awaiting the final injury diagnosis.
