In a game dubbed "The Miracle in Motown" by Jim Nantz, the Packers trailed 20-0 at halftime before pulling off a comeback in the second half. This game is well known by Packer fans for its ending. Towards the end, the Packers tried to lateral the ball to get down the field and score a game-winning touchdown. The play looked like a total bust, as Aaron Rodgers was wrapped up and brought down, seemingly ending the game. However, the Lions were called for a controversial facemask penalty that gave the Packers one more chance on an untimed down. On the next play, Rodgers threw a 61-yard Hail Mary pass to Richard Rodgers to end the game. The ball traveled 68 yards through the air, making it the longest touchdown pass in NFL history by air. The pass gave the Packers a 27-23 win. Some Packers fans refer to this play as "Hail Rodgers" or "Rodgers to Rodgers".
