NFL Referee Carl Cheffers Explains Two Pass Interference Calls

QUESTION: Can you take us through the two pass interference penalties in overtime?

CHEFFERS: The first one (2nd-and-10, Denver 47-yardline) was an arm grab.

The defender held the receiver's right arm down, which prevented him from going up for the pass with two hands. And so, that restriction of his right arm was why pass interference was called.

QUESTION: And then the second one (2nd-and-12, Buffalo 38-yard line)?

CHEFFERS: The second was early contact and an arm grab that materially restricted the receiver.
