NFL commissioner Roger Goodell snapped back at “divisive” comments about the league Saturday, hours after President Trump urged team owners to fire players who won’t stand for the national anthem.

At a political rally Friday night in Alabama, Trump griped that players who kneel for “The Star Spangled Banner” disrespect the flag and should lose their jobs.

“That’s a total disrespect of our heritage. That’s a total disrespect of everything that we stand for,” Trump said in remarks that drew loud applause.

“Wouldn’t you love to see one of these NFL owners, when someone disrespects our flag to say, `Get that son of a bitch off the field right now! Out. He’s fired! He’s fired!’” Trump said.

Goodell issued a statement via Twitter at 9:16 a.m. Saturday: “Divisive comments like these demonstrate an unfortunate lack of respect for the NFL, our great game and all of our players, and a failure to understand the overwhelming force for good our clubs and players represent in our communities.”

NFL Players Association Executive Director DeMaurice Smith attacked Trump’s comments at 6:57 a.m. Saturday, tweeting that “this union … will never back down when it comes to protecting the constitutional rights of our players as citizens as well as their safety as men who compete in a game that exposes them to great risks.”

Trump — who owned the New Jersey Generals in the ill-fated United States Football League in the early 1980s — also disparaged efforts to protect NFL players from brain injury .

“If you hit too hard … 15 yards, throw him out of the game!” Trump said at the Alabama rally. “They’re (refs and league officials) ruining the game, right?”

NFL and college football leagues in recent years have toughened rules against players who make illegal hits.
