File This Under: "Pot Meet Kettle" ... 'cause alleged bullying victim Jonathan Martin went online last night to CYBER-BULLY Justin Bieber ... telling the pop star he's an EMBARRASSMENT.

Out of the blue, Martin went on Twitter and wrote: "Never be embarrassed of who you are ... Unless you're Justin Bieber."

Obviously, an attempt at a joke ... but not a great move coming from a guy who was just talking to a class about the effects of BULLYING earlier that day.

Also, don't forget ... Martin left the Miami Dolphins claiming several players were picking on him for no reason.

Martin followed up his tweet with an attempted explanation ... saying, "Don't get it twisted... Biebs is one of the most talented artists out there... He just makes some questionable decisions."

It's been a GREAT couple of weeks for Carolina Panthers kicker Graham Gano ... 'cause right before he signed his new $12 MILLION contract, his wife gave birth to their 2nd kid ... TMZ Sports has learned.

Graham tells us ... right after his son was born (the couple's 2nd boy) ... some of his Panthers teammates sent fancy baby gifts to the house ... including a Mamaroo, courtesy of linebacker Chase Blackburn. Apparently, babies love those things.

Graham says ... even ex-teammates hooked baby Gano up with some fresh gear, including former Panthers defensive end Everett Brown -- who sent several boxes of gifts.

As for how Gano plans to celebrate the new contract, Graham tells us he can't really go crazy because of the kid -- but he does have some bachelor parties coming up and hopes his wife will give him a break from baby duty to let him go.

Yeah, good luck with that!!

Terrell Owens and Tony Hawk are messing with some serious emotions -- appearing in a commercial for a "Back to the Future" style hover board ... that's obviously some sort of joke.

But it's not just T.O. and T.H.who appear in the video -- Doc Brown himself, Chistopher Lloyd, is also in on the rouse ... along with Moby and actress Agnes Bruckner.

So far, it's unclear who's behind the video -- but it's pretty clear it's part of some kind of viral marketing campaign.

There have been rumors about a real-life hover board for decades.

Hopefully, whatever this is, helps move those plans along.

EVIL PEYTON MANNING IS BACK!!!!!

For the first time since 2008, Peyton Manning is rockin' the goatee ... in what appears to be an attempt to find a new identity after that humiliating Super Bowl loss to the Seattle Seahawks.

Evil Peyton and his facial hair surfaced at what appears to be a charity event over the weekend ... where he gave a speech, rocked a tux and even posed for pics with fans.

Somewhere, Evil Spock is laughing maniacally.

Jadeveon Clowney isn’t just a terror on the gridiron – he DOMINATES the hardwood too ... and TMZ Sports has video proof of the guy throwing down a NASTY dunk back in 2012.

Back before Clowney became a household name, the football stud played in a charity basketball game in South Carolina in May '12 ... when he was just 19 years old.

Ya gotta watch the clip ... Jadeveon threw down a ferocious dunk off a lob -- it's impressive.

We spoke to some of the guys who played in the game -- which benefited the iCHOPE Foundation for underprivileged kids -- who tell us Jadeveon's performance was super impressive and littered with some quality jams.

FYI -- Jadeveon played a little high school basketball ... and wasn't bad --averaging 9 points and 9 rebounds a game. He was better at football though.

Clinton Portis was expecting a fancy town car to take him to the airport this morning -- instead, he got a '99 Honda Civic and a driver who wouldn't put down a bucket of fried chicken ... so, of course, he took pics.

The former Pro-Bowl running back was out in Charlotte, NC on business -- and got hooked up with a car service that was supposed to take the VIP back to the airport in style.

Instead, Portis tells TMZ Sports ... "A 75 year old woman pulled up in a black 99' Civic, and there's two baby seats in the back."

"I put my bag on the baby seat and I got in the front. The lady was eating Bojangles [chicken]. I said 'this gotta be a prank."

It was no prank. This chicken-chowing chauffeur then asked Portis if HE knew the way to the airport. Not a good sign.

"We were at a red light and she punched the gas. We spun out. I couldn't stop laughing."

Sorry ladies ... and gents ... the rumored Michael Sam naked selfie just ain't him ... so says Michael's agent.

The photo has been exploding online -- with multiple websites saying the shot of a naked buff dude (which reportedly surfaced on the Grindr app) with his face covered by an iPad is the NFL draft prospect.

But Sam's agent Cameron Weiss tells TMZ Sports simply ... "The picture is not Mike."

Weiss adds, "It could be anyone. There's no face."

Cameron says the REAL Michael Sam is focused on the NFL Draft -- saying, "Michael has a few weeks to fine tune some things before his Pro Day. He'll be ready."

Darren Sharper will remain BEHIND BARS until at least Friday ... when officials will decide if the former NFL star will be dragged to Louisiana to face more rape charges.

The former New Orleans Saints defensive star was just taken from his jail cell to L.A. County Superior court -- in handcuffs -- to face the judge regarding the rape cases in California and Louisiana.

During Monday's hearing, the judge decided to take bail off the table until at least Friday, citing a "no bail warrant" out of Louisiana -- which means Sharper will remain behind bars in L.A. for the rest of the week.

In court, Sharper's attorney challenged the notion that Sharper can be held without bail -- since he hasn't been charged with a crime in Louisiana. And since he already posted bail in the L.A. case -- there's no basis to keep him locked up.

First there was Siskel and Ebert ... then Roper ... but now, there's only one name you can trust when it comes to movie reviews -- TIM TEBOW!!

Tebow hit up the Arclight theater in Hollywood on Saturday to catch the Liam Neeson airplane thriller "Non-Stop"... and on the way out, we got a genuine movie review!

Bonus -- Tim also revealed his favorite movie of all all-time ... a Mel Gibson flick ... and shocker, it wasn't "The Passion."

BALLER runs in family ... 'cause Randy Moss' daughter just dropped 63 points in a college basketball game in one of the most DOMINANT performances of all time.

Sydney Moss WENT OFF for Thomas More College in a 106-88 victory over Waynesburg in a DIII tournament in Kentucky on Friday night ... setting the DIII single-game scoring record.

Moss -- a 5'11" sophomore -- is sorta following her dad's college career path. She started at the University of Florida and then transferred to the smaller school.

Of course, Randy started at Florida State before transferring to Marshall ... where he emerged as one of the best wide receivers in the country.

NFL guru Jay Glazer -- the first guy to interview Richie Incognito about the Dolphins bullying scandal -- tells TMZ Sports ... Richie has some serious psychiatric issues and he's glad he's getting help.

Jay was leaving 1Oak nightclub in Hollywood Friday night, when our guy asked if Richie's decision to seek psychiatric help Thursday night was simply a P.R. move to win some sympathy ... but Jay shot that theory right down.

"Richie's got some issues there ... I'm glad he's getting help."

Officials in New Orleans don't just want Darren Sharper's head ... it seems they want to HUMILIATE the guy in public by parading him in cuffs though the streets of the Big Easy.

Sharper is currently jailed in downtown L.A. after New Orleans cops got a warrant for his arrest in connected with 2 alleged rapes.

We're told Sharper's lawyers tried to get him out Friday but New Orleans prosecutors objected. We're told they do NOT want the judge to let Sharper out on bail. They want marshals to come to L.A. ... shackle him and haul him back as a prisoner.

Now here's what's funky. Sources tell us Sharper has agreed to fly back to New Orleans and face the charges. It makes sense, because he's already on $1 million bail in L.A. for 2 unrelated rape charges. The judge could easily add a condition to his bail that he fly to New Orleans and return.

So why is New Orleans so crazed about making Sharper a spectacle? We're told all 5 of the jurisdictions which are investigating Sharper are all jockeying for first position. They all want to be the first to prosecute him, and there's already infighting between the agencies.

Darren Sharper ... he's not just a suspect -- he's a prize.

A second Indianapolis Colts player says he's ALL FOR bringing Jonathan Martin to the team ... telling TMZ Sports, "I think he could help us win, and that's all I care about."

We spoke with a Colts lineman -- who didn't want to be named -- who tells us he stands behind Andrew Luck ... who recently went on record saying he wants to bring his former college teammate to Indy.

"I know J-Mart some," the lineman tells us.

Richie Incognito is being held on an involuntary psychiatric hold ... but HE was the one who initially wanted to get help ... TMZ Sports has learned.

Richie Incognito was admitted to a psychiatric care unit in Arizona late Thursday night ... TMZ Sportshas learned.
