Jacksonville Jaguars quarterback Trevor Lawrence appeared to sustain a bad leg injury from his own teammate when Walker Little stepped back onto his lower ankle.
Lawrence's own weight then appeared to force his ankle to twist while a Bengals player then fell on top of him.
Lawrence at first stayed down in pain, tried to get and then crumpled back to the ground and threw his helmet to the floor and punched the ground, with his face a mix of pain and frustration.
He was helped away from the field by two trainers but was moving very slowly.
