The Latest on the NFL's national anthem policy (all times local):

6:30 p.m.

President Donald Trump is once again inserting himself into the culture war over protests by NFL athletes during the national anthem.

Trump tweeted on Friday that he "can't believe" the debate has reignited after The Associated Press reported on the Miami Dolphins formally telling players they could be punished for protesting on the field. The NFL and NFL Players Association said in a joint statement Thursday night they were halting enforcement of all anthem rules while they work out a solution.

Trump asks [url=http://www.officialpredators.com/authentic-adidas-pekka-rinne-jersey]Authentic Pekka Rinne Jersey Kids[/url] , "Isn't it in contract that players must stand at attention, hand on heart?"

No such requirement exists, but NFL owners voted in May to require players who wish to protest to remain in the locker room during "The Star-Spangled Banner."

Trump is proposing his own penalties, calling on Commissioner Roger Goodell to "take a stand."

Trump tweets: "First time kneeling [url=http://www.buffalobillsteamonline.com/trent-murphy-jersey]Authentic Trent Murphy Jersey[/url] , out for game. Second time kneeling, out for season/no pay!"

Miami Dolphins owner Stephen Ross says he hadn't decided whether to actually discipline players who protest during the national anthem when he formally told the team that the demonstrations could be punishable.

Ross said in a statement Friday that the one-sentence reference to "Proper Anthem Conduct" in the team's official discipline policy was merely a placeholder as the organization tried to comply with league rules.

The team's policy was obtained Thursday by The Associated Press and listed anthem conduct under behavior that could be found "detrimental to the club." The NFL and NFL Players Association said in a joint statement Thursday night that they planned to pause enforcement on league anthem rules while working out a resolution acceptable to players, team owners and the league.

Discord over how players should protest social injustice has put the sport at a difficult crossroads, revealing deep divisions in football itself much like those throughout the United States.

A person familiar with league protocol told The Associated Press on Friday that NFL teams were not required to create any anthem policies when they submitted their annual discipline notices to the league and players. The person spoke on condition of anonymity because details of anthem discussions between the league and players union are private.

After the Texans signed Benardrick McKinney to a five-year [url=http://www.vikingscheapshops.com]Vikings Cheap Jerseys[/url] , $50 million extension last week, it was presumed Jadeveon Clowney was next in line. The fifth-year linebacker still might be, but it might not be this season, according to John McClain of the Houston Chronicle.

Clowney [url=http://www.officialcanucks.com/authentic-adidas-derek-dorsett-jersey]Womens Derek Dorsett Jersey[/url] , the first overall pick in 2014, will make $12.3 million this year under the fifth-year option.

He still has to show he can stay healthy for the Texans to commit to him long term. Last season was the first that Clowney played all 16 games, but he spent the offseason program rehabbing a knee injury after arthroscopic surgery in January.

Texans coach Bill O’Brien said he expected Clowney to be on the field at the start of training camp July 26. That gives the Texans only a six-week window to get an extension completed, and the sides have had no substantive negotiations [url=http://www.detroitlionsteamonline.com/kerryon-johnson-jersey]Authentic Kerryon Johnson Jersey[/url] , per McClain.

Texans General Manager Brian Gaine’s philosophy is not to negotiate during the season.

That doesn’t mean Clowney will become a free agent in March. The Texans are expected to use the franchise tag on him if they can’t come to terms before that.

But Clowney’s price tag will go up with a big season. He had 9.5 sacks, 21 quarterback hits and 21 tackles for loss last season without J.J. Watt and Whitney Mercilus over the final 11 games.

Bigger numbers this season will equal a bigger pay day for Clowney.
