HOUSTON -- The explosive offenses of the Atlanta Falcons and New England Patriots will play Super Bowl LI on an indoor track.


The NFL announced the retractable roof at NRG Stadium will remain closed.

It's currently mostly cloudy and 75 degrees in Houston. The forecast did call for a slight chance of rain (15 percent) before kickoff, and minute chances (5-10 percent) during the game.

Tom Brady and Matt Ryan can both take advantage of the element-free conditions in what could be a high-scoring affair.
There was an article about how the last time the SB was played here (2004), it became extremely hot in the stadium. Closed roof combined with lights and a 4 hour game made it a sauna. Cramping could be an issue.
