Video: Watch 'dirty' submission that may get Rousimar Palhares stripped of WSOF title, suspended from MMA

If you know Rousimar Palhares, then you probably know the story by now.

Two years ago "Toquinho" put Ultimate Fighting Championship (UFC) welterweight Mike Pierce in a viciously tight heel hook for a submission victory, but failed to let go when Pierce tapped, even with referee Keith Peterson trying to pull him off.

That stunt earned Palhares his dismissal from the ZUFFA-owned fight promotion and the right to ply his trade anywhere else, assuming promoters were willing to take a risk on Palhares, who had already been fined and suspended for his submission shenanigans before.

World Series of Fighting (WSOF) decided to take that chance, but even during his run as welterweight champion, Palhares' submissions have come with accusations that he's intentionally trying to destroy people's arms and legs.

WSOF President Ray Sefo promised he wouldn't allow the Brazilian to fight dirty.

Nonetheless, judging by this video clip of his kimura lock on Jake Shields at WSOF 22 last Saturday night (Aug. 1, 2015) in Las Vegas, Nevada, it appears Palhares was up to his old tricks again, especially after he was already warned for eye gouging in round two.

Take a look:

Ouch.

Palhares refused to let go after Shields tapped out, causing his entire team to try to rush the cage, as well as Shields himself trying to swing at his opponent once he finally let go. Not just for the submission, but the fingers to the eyes during their title fight.

A frustrated Shields vents:

Palhares could be in big trouble.

"If I go back on tape and watch that fucking fight tomorrow, and if I see Palhares held too long, and did the eye poking a couple times, he might be stripped of the title," WSOF vice president Ali Abdel-Aziz told MMAFighting.com. "And Jake Shields would fight the winner between (Yushin) Okami and (Jon) Fitch for the title, and I would suspend [Palhares]."

That doesn't take into account potential action from Nevada State Athletic Commission (NSAC), which means it could be a very tough week for the Brazilian's career.

Stay tuned.
