Sometimes you see a big enough hit that the affected player's helmet comes off.
This one didn't just come off: it went FLYING.
Minnesota defensive end Tai'yon Devers got around the Colorado State offensive line almost completely unblocked, and he just unleashed everything he had on poor quarterback Collin Hill. Hill's helmet wasn't the only thing that went flying, as the hit also knocked the ball loose, allowing Minnesota to recover in plus-territory.
Minnesota was able to get a field goal after the recovery to extend their lead to 17-7.
