Mojo Muhtadi put the break in dancing over the weekend … suffering a GNARLY shoulder injury while partying with Ryan Cabrera in Las Vegas!

The ex-WWE Superstar turned TMZ Sports TV show co-host was at Ghost Bar at the Palms Saturday night for Cabrera’s performance … when a dance battle busted out.

Never one to turn away from an opportunity to dance, Muhtadi *attempted* a diving shoulder roll … that went very wrong.

But, injury or not, Muhtadi, who was in Vegas hosting several events around WrestleMania weekend, wasn’t going to cut the night short and head to the hospital.

Instead … Mojo continued to party, and then returned to his hotel room for the night, hoping a solid few hours of sleep would be all the medicine he needed.

Sunday morning came and the shoulder was still busted, so MM headed to see a local doc … where they took this doozy of an X-Ray.

The diagnosis? A grade III AC (acromioclavicular) joint (total) separation.

Thankfully, he doesn’t need surgery … docs say after a couple of weeks in a sling, he’ll be nearly as good as new. In fact, Mojo attended a full day of events on Sunday … which even impressed his pals, including a former wrestler, who is no stranger to crazy injuries.

“Some things never change—Dean has always been known for bringing the hype. But seeing him return on Day 2 after a shoulder injury and finish the contest gave a whole new meaning to what being HYPE really is,” Mandy Sacs told us.

As for the man performing at the time of the busted shoulder … Cabrera said it was an unforgettable night.

“Watching Mojo split his shorts during the dance battle at my set was the highlight of my DJ career!!! It is a true testament to his dedication to winning, the man even dislocated his shoulder.  I’ll never unsee what I saw that glorious evening!” Ryan Cabrera said.

A couple of identical twins from Australia are going viral for an interview they gave to a local news outlet covering an alleged armed carjacker … because they’re talking at the same time and saying the exact same things.

Ya gotta see the video … Bridgette Powers and Paula Powers are totally on the same page as they recall how they and their mother found themselves in the middle of a scary incident on Steve Irwin Way in Queensland.

The twins have the same voice, the same cadence and the same thoughts … and it’s pretty wild to hear them talking in unison.

Former college football star Justin Blackmon couldn’t fit in the back of a cop car during his public intoxication arrest … with a police report obtained by TMZ Sports stating a larger vehicle was required to transport him to jail.

The 35-year-old ex-Oklahoma State Cowboys receiver’s most recent run-in with the law made rounds on social media over the weekend … with sports fans noting the drastic change in Blackmon’s appearance in his mug shot.

According to the incident report, OSU cops responded to a call regarding a “larger black male” laying on the ground at 1:32 AM on Saturday morning.

According to the report, he repeatedly stated he was going to “Stillwater” … but when told that was a town and not an address, he replied by admitting he did not live in that area and said, “You got me.”

Cops claim Blackmon then turned around and placed his hands behind his back … and was informed he was under arrest for public intoxication.

Cops noted two sets of handcuffs were used “due to his body size and the girth of his wrists” … and when he was escorted to a patrol unit, he was “unable” to fit in the back seat “due to his body size,” according to the report.

Eventually, another unit responded to the location … and Blackmon was placed in a larger patrol car and taken to jail for booking and processing.

Blackmon is listed as 6’2″, 230 in the police report … which is about 20 lbs heavier than he weighed during his time on the gridiron.

After a stellar career at OSU, Blackmon was the fifth overall pick to the Jacksonville Jaguars in the 2012 NFL Draft.
