PITTSBURGH — The NFL is reviewing a post on Facebook by Pittsburgh Steelers wide receiver Antonio Brown, a spokesman for the league confirmed Tuesday.

Brown began streaming live via Facebook Sunday from the Steelers’ locker room after the team won its playoff game against Kansas City.

The All-Pro wide receiver also happened to catch coach Mike Tomlin indelicately describing the New England Patriots, Pittsburgh's opponent in the AFC Championship game.

Tomlin's word choice - an expletive - didn't bother his players as Brown's decision to throw back the curtain on what is usually a private moment.

"Personally I'd like some of that stuff sacred," long snapper Greg Warren said Monday. "But this is a changing world, a changing environment. I can't be some old guy stuck under a rock, that's for sure."

Brown's 17-minute video collected more than 900,000 views in a few hours before being removed (though it lives on through YouTube).

It included players dancing and Tomlin - who was out of the shot and unaware it was being filmed but who could be heard clearly in the packed locker room - beginning his postgame speech by telling his team to "say very little moving forward" then adding "we spotted those (expletive) a day and a half."

NFL spokesman Brian McCarthy shared the NFL’s game day social media use policy with Channel 11 News:

"The use of social media by coaches, players, and other club football operations personnel is prohibited on game day (including halftime) beginning 90 minutes before kickoff until after the post-game locker room is open to the media and players have first fulfilled their obligation to be available to the news media who are at the game."

McCarthy said potential discipline for violation of the policy is a fine.
