Minnesota Vikings left tackle Christian Darrisaw needed to be helped off the field during Minnesota's "Thursday Night Football" clash with the Los Angeles Rams, and he will be out for the season.

With 35 seconds left in the first half, the Vikings elected to call a run play from their own 3-yard line rather than taking a knee. During running back Aaron Jones' 2-yard run, Darrisaw's left leg got rolled up on by Rams rookie safety Jaylen McCollough, who was making the tackle.

Darrisaw fell to the turf after the play and immediately grabbed at his left knee. The Vikings' medical personnel tended to the star tackle on the field before assisting him in a walk back to the locker room. Darrisaw appeared unable to put much weight on his left leg as he made his way off the field.

The Vikings ruled the left tackle out for the remainder of the game with a knee injury and said Friday that he would need season-ending surgery.

Christian Darrisaw injury updates

Darrisaw needed assistance from Minnesota's medical personnel to walk back to the locker room after suffering a knee injury in the final seconds of the first half.

The tackle took a hit to the outside of his left knee while he was engaged in a block on a run play from a Rams defender making a tackle. Offensive lineman David Quessenberry replaced Darrisaw on the final play of the first half, a quarterback kneel.

After the game, head coach Kevin O'Connell confirmed to reporters it was a left knee injury.

Friday, he provided another update.

"I was holding out hope last night that maybe the imaging would reveal a less significant injury, but unfortunately that is not the case," he told reporters. "He did sustain a significant knee injury to his left knee and will require season-ending surgery. He will go on injured reserve today."
