Rapper Dmx is one step closer to stepping into a boxing ring with America's most infamous Neighbourhood Watch volunteer, George Zimmerman, after entering negotiations for a charity fight night. The Party Up (Up In Here) hitmaker put his name forward as a potential challenger after event promoter Damon Feldman revealed he was looking for opponents for Zimmerman, who was acquitted in 2013 of murdering unarmed black teenager Trayvon Martin during an altercation in Florida. Last week (ends31Jan14), The Game, who has an image of Martin tattooed on his leg, admitted he would relish the chance to beat up Zimmerman, but Feldman has since decided to put DMX to the test by selecting him from a pool of 15,000 applicants. The rapper recently vowed to "beat the living f**k" out of Zimmerman, adding, "I am breaking every rule in boxing to make sure I f**k him right up." DMX has verbally agreed to take part in the Celebrity Boxing bout, but his representative, Domenick Nati, tells TMZ.com the rapper has yet to be presented with an official contract for the three-round bout. Details about the clash are expected to be announced in a press conference next week (begs10Feb14).
