Bland jumped a pass intended for Jonathan Mingo and knew exactly what to do when he dove and caught it.
Bland tied Eric Allen (1993), Ken Houston (1971) and Jim Kearney (1972) with his fourth pick-six and still has seven games to break it.
Young is 15-of-27 for 121 yards with a touchdown and an interception. He has taken five sacks, including three by Micah Parsons. That's the most Parsons has ever had in a single game.
