Philadelphia Eagles running back Ja’Quinden Jackson left Gillette Stadium in an ambulance during Saturday night’s preseason game.
Jackson was injured on the opening kickoff.
He appeared to take a knee to the head from Patriots running back Lan Larison after diving at Larison’s legs to make a tackle. Jackson was knocked out, and both arms went into the fencing position.
Medical personnel immediately began work on Jackson before he was placed on a backboard and then a stretcher and placed into the ambulance, which came onto the field.
