Robert Griffin III was physically restrained during a heated confrontation at an off-season training session in Tallahassee ... and TMZ Sports has the video.

Donald Trump's Chicago hotel is suing an NFL player and his bride for allegedly stiffing the hotel on a big wedding bill, but it seems from the lawsuit something went wrong during the reception.

Tennessee Titans linebacker Justin Staples tied the knot with Amber last June and, judging from the video, the reception was fun and lovely. They even had Afterglow Snacks, which, based on the menu, may have included cheeseburger sliders, buffalo wings, fried mac and cheese bites and BBQ spiced waffle fries.

Justin and Amber apparently drove a hard bargain before the wedding, because Trump International Hotel and Tower dropped their proposed fee to $79,484.

According to the lawsuit, Justin and Amber paid $30k, but that was it.

Now, here's a big clue. According to the lawsuit, at the end of the reception, the hotel slashed another $5,062.13 from the bill, so it seems like something happened ... maybe food wasn't served, the cake was wonky, the bar ran out of liquor, the joint shut down too early ... something.

Ex-NFL star Shawne Merriman says he's taking on a new challenge as the owner of a NASCAR racing team ... telling us he LOVES the sport and wants to inspire black kids to love it too.

Why NASCAR? SM told us he's a HUGE racing fan, having caught the bug at a race some years ago ... and said he wants to do something to promote his passion to black youth.

"We thought NASCAR would be a huge deal for us, kinda going into a different demographic. There's not a whole lot of minorities looking to be into NASCAR."

Merriman says he thinks once black kids are introduced to the vroom-vroom life -- you might see more of them get involved with NASCAR ... maybe even choose that sport over the NFL or the NBA.

Reports say that's when Mayfield went nuts, cussing and making a scene.

The report says Mayfield had slurred speech, trouble walking and was covered in food. Mayfield allegedly sprinted away from the officer and once tackled, refused to cooperate.

The QB and Heisman hopeful was arrested for public intoxication, disorderly conduct, resisting arrest and fleeing.

A statement from the school says, "We are aware of the matter and are learning the details."

"Whether you respect the person who holds that position or not, you respect the office that he holds," McIlroy says.

"This wasn't an endorsement nor a political statement of any kind. It was, quite simply, a round of golf. Golf was our common ground, nothing else."

"I've travelled all over the world and have been fortunate enough to befriend people from many different countries, beliefs and cultures."

"To be called a fascist and a bigot by some people because I spent time in someone's company is just ridiculous."

Muhammad Ali Jr. was detained for 2 hours at the Fort Lauderdale-Hollywood International Airport ... and he's ready to sue because he thinks it's because he's Muslim.

Ali Jr.'s spokesman, Chris Mancini, tells TMZ ... his client was returning from Jamaica with his mother, Khalilah Ali -- Ali's first wife -- on February 7 when immigration officers stopped them. She got through, but he was taken to a small room for 2 hours and questioned.

Mancini says Ali's 44-year-old son was asked twice if he's Muslim, and also where he got his name. He was traveling on a U.S. Passport.

Ali Jr. is looking into suing the U.S. Treasury and Homeland Security over the incident. Mancini believes it hints at a larger issue of profiling and discrimination. He's interested in filing the lawsuit as a class action.
