Ultimate Fighting Championship (UFC) is rapidly plugging holes in its UFC 148 fight card, currently scheduled for July 7, 2012 at the MGM Grand Garden Arena in Las Vegas, Nevada, according to a tweet from UFC Brazil (via Porto do Vale Tudo).

Talented 155-pound striker extraordinaire, Melvin Guillard, has reached DEFCON 2 from a career standpoint, having dropped consecutive losses to Joe Lauzon and Jim Miller and getting finished in each of those two bouts. He'll try to prove himself worthy of future fisticuffs at the expense of Fabricio Camoes, who can seemingly do no wrong in his last couple of fights.

After getting strangled by Kurt Pellegrino at UFC 111 back in March 2010, "Marango" returned to the regional scene, racking up back-to-back wins over Steve Lopez and Efrain Escudero. He was impressive enough to get a call back to the big show, where he promptly disposed of Tom Hayden at UFC on FX via first round rear naked choke.

Watch that neck, Mr. "Young Assassin."

UFC 148 is expected to feature a bantamweight title fight between TUF 15 coaches (and bitter rivals) Dominick Cruz and Urijah Faber, in addition to middleweight match-ups between Rich Franklin vs. Cung Le and Tim Boetsch vs. Michael Bisping.

And let's not forget Tito Ortiz's retirement fight rubber match against Forrest Griffin.
