Thug-jitsu is back, son.

The UFC continues to Frankenstein its upcoming "Fight Night 22" fight card, this time after former Ultimate Fighter (TUF) 6 Champion Mac Danzig was forced to withdraw from the Spike TV event following an injury to his pectoral muscle and a pinched nerve.

MMA Weekly brings confirmation of the change in plans, and also indicates that fellow TUF champ Efrain Escudero will abandon John Gunderson at the undercard altar to step in for the Vegan warrior in the night's co-main event.

Enter Yves Edwards.

The UFC veteran returns to the Octagon for the first time since a TKO loss to Joe Stevenson way back at UFC 61: "Bitter Rivals" over four years ago. In addition to the UFC, the master of Thug-jitsu has fought for PRIDE, Strikeforce, EliteXC and just about any other promotion you can think of.

The Texan, fresh off a Bellator 25 win over Luis Palomino, has been mixing it up since late 1997 and would no doubt like to leave UFC fans with a better memory than the one left by his last performance under the Zuffa banner.

The only thing standing in his way are the "Quick Guns" of John Gunderson.
