It's time to separate the men from the boys.

Mark Munoz will get a chance to prove he truly is one of the top 185-pound contenders when he faces grappling wizard and former division number one contender Demian Maia at the upcoming UFC 131 pay-per-view event scheduled for the Rogers Arena on June 11 in Vancouver, British Columbia, Canada.

MMAmania.com confirmed the bout was in the works earlier today.

Munoz (10-2) is fresh off a first round technical knockout stoppage over C.B. Dollaway at UFC on Versus 3 earlier this month. "The Philippine Wrecking Machine" has shown consistent improvement since a debut loss to Matt Hamill just over two years ago.

In fact, the All-American wrestler out of Oklahoma State University is 5-1 since his loss to "The Hammer" and has developed a trademark ground-and-pound style that led him to wins over division stalwarts Ryan Jensen, Kendall Grove and Aaron Simpson.

But will he survive long enough on the ground to implement it?

Despite his world class jiu-jitsu, Maia hasn't secured a finish in over two years. After an electric debut that saw him capture his first five contests, the next five proved to be a bit rockier as the Brazilian went 3-2 with lopsided losses to Nate Marquardt (UFC 102) and Anderson Silva (UFC 112).

He most recently outpointed Kendall Grove at The Ultimate Fighter (TUF) 12 Finale back in December 2010.

UFC 131 will feature a main event between heavyweight contenders (and TUF 13 coaches) Junior dos Santos and Brock Lesnar while Kenny Florian makes his featherweight debut against Diego Nunes.
