GETTING DOWN!!!
Mojo Muhtadi put the break in dancing over the weekend ... suffering a GRARLY 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.
The 6'4", 269 lb. former Andre The Giant Battle Royal champ landed directly on his left shoulder .
