Michael Irvin says Dak Prescott needs to be studying something ... and it ain't psychology, telling TMZ Sports that as long as Dak is a Cowboy, the playbook comes 1st, and the PhD 2nd.

Prescott recently said he was interested in returning to Mississippi State to get his PhD in psychology, so when we got Irvin at LAX he said he was all about it, with one catch.

"I want him to study... plays first."

Michael's point? Prescott has about $200 million worth of future earnings waiting for him in the NFL if he doesn't lose his focus on pesky things like bettering himself and expanding his mind.

Rex Ryan and his brother, Rob Ryan, have both been named in a police report by a man who claims the NFL coaches assaulted him at a bar in Nashville over the weekend.

A rep for the Metro Nashville Police Dept. confirms Matthew Havel (from Colorado), filed a simple assault report against the Ryan brothers over an incident at the Margaritaville bar on Saturday.

A snippet of the incident was captured on video -- and shows Rob grabbing another man by the neck. It's unclear what prompted the skirmish.

Former San Francisco 49ers cornerback Tramaine Brock has been hit with a felony domestic violence charge after he allegedly attacked his GF in front of their 1-year-old child.

Officials say 28-year-old Brock -- who played with SF from 2010 to 2016 -- punched his girlfriend in the face on April 6 at a Bay Area home after a disagreement about what TV show to watch.

He then allegedly tried to strangle her multiple times -- one of the times she was holding the child. The 49ers cut Brock right after he was arrested.

Brock -- who was also charged with misdemeanor child endangerment -- faces up to 5 years in prison if convicted on both counts.

Bill Belichick finally addressed Gisele's claim that Tom Brady has suffered multiple concussions over the years -- despite no formal injury report from the Pats -- saying dealing with injuries is "not really my job."

The Patriots head coach addressed the media in Foxborough early Tuesday morning and was asked for the team's response to the comments Gisele made on "CBS This Morning" back in May.

Belichick deflected -- though he said the team files injury reports "in compliance with league guidelines."

When pressed further about how he deals with possible player injuries, Belichick passed the buck ... saying when it comes to the "injury situation" ... "that's not really my job."

"That's what we have medical staff for."

Dr. Dak Prescott?!

The Dallas Cowboys star says he's not done stackin' up college degrees ... revealing his plans to hit the books and pursue a PhD in psychology!!

The NFL's Rookie of the Year -- who already has his Bachelor's AND Master's degree from Mississippi State -- joined the Talk of Fame Network to discuss his desire to keep learning both on and off the field.

"Just getting my degrees has helped me immensely, just within the game of football and with people, just making me more educated in general," Dak says.

"It's something I continue to do. I'm actually continuing at some point either when I'm done (playing) or one offseason, I want to start working on my doctorate. So, I mean, it's very important to me."

Cool stuff at the 2 minute mark ... especially coming from someone who dominated his first year in the league.

NFL Hall of Famer Cortez Kennedy was hospitalized for swollen legs just days before he died ... and the information could hold the clue as to why he passed away.

TMZ Sports obtained the police report in the 48-year-old's death -- which says Kennedy had called a friend the night before he died because he was concerned about his health.

During the call, Kennedy said he was feeling dizzy and asked the friend to check on him in the morning to make sure he was okay.

Sadly, by the time the friend went to Kennedy's Orlando, FL home on May 23, he was already dead.

Investigators say medical paperwork found in Kennedy's home confirm he was hospitalized from May 10 to May 15.

10:00 AM PT -- Cops say they also found an "unknown liquid" in Lewis' car. They sent it to a testing lab and will file more charges if it comes back as an illegal substance.

NY Giants receiver Roger Lewis was arrested for operating a vehicle while impaired over the weekend ... TMZ Sports has learned.

Lewis' 2012 Audi was initially pulled over on June 4 in Reynoldsburg, Ohio for speeding and tinted windows. But during the stop, cops tell us they smelled weed and noticed signs of intoxication.

They asked Lewis to take a breathalyzer test, but he refused.

The 23-year-old was taken into custody around 5 AM on an OVI charge. He was released to a sober friend on his own recognizance.

Lewis -- an undrafted free agent back in 2016 -- was part of Odell Beckham's infamous Miami yacht party with Trey Songz back in January. He had 2 TDs last season.

We've reached out to the Giants and Lewis' rep for comment ... so far, no word back.

Stedman Bailey is still focused on getting back in the NFL -- nearly 2 years after getting shot in the face -- and says he's undergoing one last surgery to increase his chances for a comeback.

Bailey was a stud WR for the Rams before gunmen blasted on him while he was sitting in a car with family members in Nov. 2015. Stedman was hit twice in the head and is lucky to be alive.

The 26-year-old was waived by the Rams in 2016 -- but he's been training like a maniac in an effort to get back on the field.

"Got a procedure coming up that WILL increase my chances of stepping back out there drastically," Bailey says.

"I damn sure owe it to myself to try everything within my power to get back on the field."

Bailey says if he's not medically cleared after this surgery, he'll quit pro football and move on with his life.

"After this procedure if doctors think it's too risky for my health and well being then I'll accept that this door has closed in my life ... but until then I'ma ball until I fall!"

President Donald Trump has a new golf buddy ... Peyton Manning.

The two hit the links together at Trump National Golf Club in Virginia on Sunday -- along with Republican Sen. Bob Corker from Tennessee (same state where Peyton played his college ball).

The group reportedly spent roughly 4 and a half hours playing -- no word on who emerged victorious.

Manning was in town to receive the Lincoln Medal in D.C. later that night.

Michael Floyd begged the judge in his DUI case to remove his ankle monitor before Vikings training camp began -- because he was worried the device could wreck his ankle if he played with it on.

The good news for Floyd ... the judge gave him the thumbs-up.

Floyd was previously ordered to wear the alcohol monitoring device while on house arrest as part of his sentence for driving while insanely drunk in Arizona during a December incident.

But Floyd -- a WR for the Vikings -- knows running patterns with a giant gadget on your ankle is dangerous so he asked the judge to cut him loose.

In court documents obtained by TMZ Sports, Floyd argued ... "Due to the high impact sport, attempting to run and high velocity tackling, the ankle device itself could be damaged and more importantly cause severe damage to the [Floyd's] ankle resulting in possible broken bones."

The judge agreed -- removed the ankle device -- and instead ordered him to submit to random breath testing on a GPS-enabled device.

Troy Aikman started off his European vacation with a bang -- proposing to his girlfriend on Lake Como on Friday ... and she said, 'Yes!'

The Cowboys legend has been dating Capa Mooty -- who's been described in the media as a "Dallas fashion icon."

The two flew to Italy on Thursday to begin a euro-trip together -- she clearly didn't know it would be an engagement vacation.

They've been dating since at least 2016. No word on how they met. Both Troy and Capa each have 2 children from previous relationships.

This will be Troy's second marriage. He divorced his first wife, Rhonda, back in 2011.

Mazel!

Adam "Pacman" Jones is taking Joe Mixon under his wing -- and treated the Bengals rookie to a night out at the Future concert this week ... TMZ Sports has learned.

Turns out, Jones is pretty tight with Future -- they grew up together in Atlanta -- and the rapper hooked the Bengals star up with tickets to his Cincinnati concert Wednesday at the Riverbend Music Center.

We're told Jones invited Mixon as his guest -- and they had a blast together and took pics with fans.

So, why Mixon? We're told Jones quietly mentors a lot of young players on the team -- including Joe -- and he likes the guy.

The L.A. Rams are breaking even more ground in the LGBTQ arena -- becoming the 1st NFL team ever to officially sponsor a gay pride event.

The team has joined up with Venice Pride -- the organization behind the massive Venice Pride block party -- and has sponsored the blue lights in the letter "C" in the famous VENICE sign.

Each letter in the sign will be lit up with a different color -- just like the rainbow LGBTQ pride flag. The event begins June 2.

A Rams spokesperson issued a statement saying the team is proud to "stand in alignment with the LGBT community that is such an important part of the fabric of Los Angeles."

"Inclusion has always been a valued part of our organization and we see this as a unique way to publicly celebrate the diversity that makes this community so special."

Of course, the Rams made history in 2014 when they drafted Michael Sam -- the first openly gay player to enter the NFL Draft.

The Indianapolis Colts lineman who attacked a taxi cart driver in Arizona and then threatened police just got 2 years probation ... but he still faces even MORE punishment.

As we previously reported, 25-year-old David Parry went on a crazy drunken bender in Scottsdale, AZ on Feb. 25 -- that culminated with the 300-pounder puking his guts out in a jail trash can.

During the incident, Parry allegedly carjacked a taxi cart, drove it around -- and then called police "f**king f**gots," "fat f**ks" and "p**syboy."

The case was divided to be prosecuted in two separate courts.

Maricopa County Superior Court handled 3 of the charges -- including misdemeanor disorderly conduct, robbery and felony attempt to commit unlawful means of transportation.

The other charges, mostly related to the DUI part of the incident, are being handled by Scottsdale City Court.

Today, Parry was punished in MCSC -- getting 2 years probation as part of a plea deal.

San Francisco 49ers defensive tackle Arik Armstead is winning the off-season -- getting himself a brand new GF who might be the most smoking hot future M.D. ever.

Arik, who's going into his 3rd year in the NFL, is dating Mindy Harwood -- better known on Instagram as Mindy Sittinpretty -- an IG force whose insane curves have brought her over 350k followers.

Want more perfection? Mindy is a very recent grad of The University Of Buffalo medical school which means she's brains AND body.

Check out the pics ... it's good for your health.

She was caught in the middle of one of the craziest NFL love triangles ever -- but model Jena Frumes says she cool with Antonio Brown after he left her to get back with his pregnant girlfriend.

The story made all sorts of headlines when Brown left his pregnant girlfriend, Chelsie, for an off-season romance with Jena Frumes ... only to leave Frumes to go back to Chelsie in April.

Frumes was PISSED at the time and tweeted that Brown used her to piss off Chelsie -- so, when we saw her out in L.A. this week ... we had to ask if she was still upset.

Good news for AB ... Frumes says they're cool again -- and she would even draft him on her fantasy football team.

Smoooooth.
