The NFL has a backup plan for the Winter Classic if weather interferes with the annual event. Rain showers and temperatures in the low 50s are being forecast for the Capitals-Penguins outdoor game Saturday at Heinz Field. While the game is set to start at 1 p.m. ET, it could be pushed back to later in the day if improved conditions are expected. The NHL has also reserved Heinz Field for Sunday, when the forecast is more favorable.
