Former NBA superstars Shaquille O'Neal and Charles Barkley were on the set of TNT's "Inside the NBA" Wednesday night when a wrestling match between the two broke out. Bouncer Chronicles sources said they won't meet in the octagon for a mixed martial arts match as planned.

O'Neal said he would definitely kick Barkley's ass because "I'm from the streets and he's not." The "Diesel" further taunted Barkley by saying "Barkley backed out...I'm serious I would kill him; that's no joke, you can quote me on it."

Judging by the first round of action Shaq has Barkley's number. He has been doing mixed martial arts training that includes boxing, muay thai and wrestling for the last 10 years at Jonathon Burke's Gracie Gym in Orlando, Florida.
