The Denver Broncos provided the world with one of the most exhilarating endings of the 2016 season on Sunday when rookie Justin Simmons leaped into the backfield to block the potential game-winning extra point. Will Parks scooped up the ball and scampered for the two-point score to give the Broncos a road win over the New Orleans Saints.

The play went under review when it looked like Parks could have stepped out of bounds on the return.

The NFL's senior vice president of officiating Dean Blandino gave a detailed description of why the play was ruled called on the field.

That's great stuff from Blandino.
