For only the third time in NFL history, a game ended on a "walk-off sack," according to SportsCenter. On 3rd and 10 with the ball on the Cincinnati Bengals' 8-yard line, Andy Dalton dropped back and seemingly out of nowhere, Cameron Wake of the Dolphins came crashing in and sacked Dalton in the endzone. And just like that, the 'Fins were victorious over the Bengals, 22-20.

What a way for a game to end.
