Javonte Williams was taken to the locker room on a cart during the Denver Broncos' 32-23 loss to the Las Vegas Raiders on Sunday.

Williams stayed down on the field after a 1-yard loss on the first play of the second half. Athletic trainers checked his right knee before he was helped to the injury tent on the Broncos' sideline.

The running back left Allegiant Stadium on crutches as some of his teammates offered quiet encouragement.

"We're still evaluating," Nathaniel Hackett said. " ... We want to be sure we get MRIs and get a feel there."
