From Wikipedia:
With the game-time temperature at 4 °F (−16 °C), the coldest National Football League game since the Ice Bowl of December 31, 1967, the first quarter contained nothing but punts and interceptions, with Cleveland's Ron Bolton and Oakland's Lester Hayes each recording one of the latter.
Trailing 1412 with less than a minute remaining in the game, the Browns had the ball on the Raiders' 13-yard line and were in position for a potential game-winning field goal. Sipe conferred with head coach Sam Rutigliano, who called a pass play, "Red Slot Right, Halfback Stay, 88," and instructed Sipe to "throw it into Lake Erie" (throwing the ball out of play as it was only 2nd down), if the play was anything less than wide open. On the next play, Sipe forced a pass to tight end Ozzie Newsome. However, it was intercepted in the end zone by Raiders safety Mike Davis, who had cut in front of Newsome's square-out pass route, putting an end to the Browns' season. Oakland subsequently advanced to the AFC conference championship, where they defeated the San Diego Chargers and went on to win Super Bowl XV against the Philadelphia Eagles.
It was da@@ed cold, I tell you. Especially from the bleachers
