Willie Nelson can take BOTH Diaz brothers at the same time ... at least when it comes to smoking weed.

The country music legend (and pot icon) was proudly displaying his new boxes of the new Nick and Nate Diaz line of marijuana cigarettes.

The company behind the pot products say "Nate's Energy" weed is a pre-workout blend and "Nick's Recovery" is to help athletes post-training.

Or, if you're Willie Nelson ... pre-show, post-show?

Casper Smart says there's a reason he's putting in work on the MMA mat ... and it's not to beat up J Lo's next boyfriend ... telling TMZ Sports he wants to be an action movie star!

We got Casper out in Vegas and talked to him about his MMA training, which he's taken quite seriously since he starred in the combat themed movie "Street" a couple years ago.

Smart says anyone who thinks he's doing all this work for a shot at the UFC is super WRONG ... telling our guy he's getting his rounds in so he can be the next big action star.

BTW -- we also ask Smart who he thinks would win in a fight between him and Drake, Lopez's last (rumored) flame.

Tyron Woodley said an emotional pre-fight encounter with a woman whose daughter recently died inspired him in the 5th round at UFC 209 ... and he's shipping her his championship belt.

It's a pretty incredible story ... Woodley says the woman (who works at T-Mobile Arena where the fight was being held) approached him before UFC 209 and told him that she had lost her daughter recently and watching his fights had helped her get through the tough times.

Woodley says he thought about the woman and her family during the fight and it motivated him in the championship rounds.

After defeating Stephen "Wonderboy" Thompson, Woodley says his team tracked down the woman -- and he plans to send her his belt because he knows how much it means to her.

UFC champ Tyron Woodley is going after his boss in a big way -- blasting Dana White for publicly saying he didn't think Tyron should have won this weekend ... but Dana says Tyron needs to shut up and let his fists do the talking.

Woodley tells TMZ Sports he found it "distasteful" for White to say the judges scored the fight incorrectly by awarding Tyron the majority decision over "Wonderboy" Thompson at UFC 209.

"That's like me coming out as a fighter and saying, 'I don't think you did a good job promoting the fight' ... which I don't. I don't think they did a good job promoting me as champion."

Woodley says he vows to be a "tough guy to deal with" moving forward.

We spoke to White who essentially said if Woodley would have beat Wonderboy's ass like he promised, there wouldn't be an issue.

"Tyron Woodley came out and said he was going to destroy Thompson and there would be no question he was the champ. Well guess what? There's questions again."

"Let me tell you what ... when you have a performance like you did at 209 and you get booed for 5 straight rounds and then people are booing so loud you can't even do your interview, you should probably just take your lumps and move on. Get your next fight as fast as you can and try to put that performance behind you."

Khabib Nurmagomedov's manager says the UFC fighter's medical scratch this weekend was a VERY costly decision ... but the team ultimately decided his health was more important than money.

We spoke with Ali Abdelaziz who says Khabib was in more pain during his weight cut before UFC 209 than he's ever seen -- despite keeping the same weight cutting routine he uses for every fight.

Ali says Khabib initially refused IV fluids when he was taken to the hospital Thursday evening -- but ultimately caved because the pain became unbearable.

Question: How does Nate Diaz deal with hecklers?

Answer: He cusses 'em all out -- and then takes selfies with 'em.

That's exactly how it went down in Vegas this weekend when a bunch of Khabib Nurmagomedov supporters began chanting at Nate ... and it was hilarious.

UFC star Michael Bisping's breaking major movie news ... telling TMZ Sports there's ANOTHER 'xXx' movie in the works ... and he's been tapped to appear in it!

Bisping already had a role in the most recent installment of Vin Diesel's action franchise, "xXx: Return of Xander Cage" ... a movie that made more than $300 MILLION at the box office.

The Count says things went so well he's already been contacted for the next flick and will start filming over the summer.

He's also got another movie in the works with Gerard Butler.

Plus, that superfight with George St-Pierre.

TMZ Sports POP QUIZ TIME!

Why did UFC star Fabricio Werdum bring a big ass 48" TV to the airport?

A. He's holding it for a friend until they come and pick it up.

B. He's opening a stand-up comedy bar in Brazil, and bought the TV in America to bring it there.

C. He's hoping someone will try to steal the TV, so he can practice kicking the hell out of people.

D. He likes his in-flight entertainment BIG.

Cody Garbrandt says he's ready to release video footage showing him knocking out T.J. Dillashaw during a training session ... unless his UFC rival does one very humiliating thing.

Cody is out in Vegas for UFC 209 where he confirmed the video is very real -- claiming it was shot sometime around 2012.

The reigning bantamweight champ says he's sick and tired of T.J. claiming the KO never happened and he's wants to release the footage to protect his credibility.

The real reason Tony Ferguson won't fight Michael Johnson -- "He remembers the last time I whooped his ass!"

That's what the UFC fighter told us in Vegas moments ago when asked why he thought Ferguson wouldn't agree to let him replace Khabib Nurmagomedov this weekend at UFC 209.

As we previously reported, Dana White was down to let Johnson step in at the last minute -- but Ferguson said no.

Johnson admits he understands why Ferguson wouldn't want the bout -- "It's a risky fight for him" -- but says the dude needs to STOP DODGING HIM!

Michael Bisping says Georges St-Pierre is straight-up CRAZY if he thinks he'll be able to "stroll off the couch" after a 3 year break and beat him ... adding, "The guy's out of his f**king mind!"

Bisping was extremely complimentary of GSP's fighting skills -- "He was one of the greatest fighters this world has ever produced" -- but says the guy has no chance when they face off later this year.

UFC star Tyron Woodley says he beat Stephen "Wonderboy" Thompson so badly during their fight back in November, the dude suffered a concussion ... and he should NOT be fighting at UFC 209.

Problem is ... Dana White says he's full of crap.

We spoke to Woodley on his way to Las Vegas for this weekend's fight -- and he told us straight-up, "[Wonderboy] should have had a 90 day suspension. It was was a tough fight. He had a concussion during that fight."

Woodley added, "Any other fighter who has a concussion, you are automatically awarded a 90 day suspension."

FYI, Thompson was never officially diagnosed with a concussion by a doctor and Dana White tells us Woodley's comments are off base.

"I'm gonna go ahead and take the advice of the best doctors in the country over Dr. Tyron Woodley," White tells TMZ Sports.

In an unrelated note, Woodley says his kids are following in his insanely athletic footsteps ... including his 2-year-old girl.

Now that Dana White has confirmed Michael Bisping will fight Georges St-Pierre ... here's your friendly reminder that Bisping promised to beat down GSP ... with ONE ARM!!

We spoke with Bisping back in October when the UFC was still trying to put the fight together and "The Count" told us GSP was the one causing all the problems.

That's when Bisping made the 1-arm offer ... and it's pretty funny.

It was blood, sweat and iced coffee for Ronda Rousey on the set of "Blindspot" ... where the UFC legend was decked out in an orange prison jumpsuit for her guest role on the show.

UFC star Stephen "Wonderboy" Thompson says he's sick of hearing about a possible Conor vs. Floyd fight ... telling TMZ Sports it seems like a desperate move from Floyd to save the sport of boxing.

Thompson was out in NYC promoting his upcoming rematch with Tyron Woodley at UFC 209 ... when we asked how UFC fighters feel about constantly answering Mayweather questions.
