As the NFL returns to action following the terrorist attacks in Paris, the National Football League has asked that teams hosting games this weekend hold a pre-game moment of silence prior to kickoff. NFL spokesman Greg Aiello tweeted Commissioner Roger Goodell’s request tonight. NFL spokesman Brian McCarthy said the moment of silence will be observed before the National Anthem at each game.

The NFL didn’t say whether other expressions of support for the citizens of France would take place. There are likely to be French flags in the stands and on the field, as happened at many college games on Saturday. Players might pay pay tribute with messages on their shoes, eye strips, or elsewhere — and hopefully the league won’t issue fines if they do.
