Itching for more action in the ring? You can take off the gloves and go no holds barred in Fight Night Champion's Bare Knuckle DLC packs.

The new matches use the prison rules from the game, which means anything goes. With no ref, you can headbutt or hit below the belt all you want. With no round structure, the boxers only go to their corners after someone knocks their opponent on their keister, and the last man standing is the victor. The mode also features a separate set of leaderboards, belts, and awards. 

Two tiered pricing structures are in place for the DLC. You can spend 800 MS points ($10) to pick up the Heavyweight Legends Pack, which features the bare knuckle boxing along with five legendary fighters – Jack Johnson, Rocky Marciano, Jack Dempsey, Joe Louis, and Floyd Patterson. If you don't want the boxers, opt for the Bare Knuckles Boxing Pack, which only costs 320 MS points ($4).

Because of the rogue nature of the game mode, a few boxers declined to participate. Muhammad Ali, Mike Tyson, Oscar De La Hoya, George Foreman, Joe Frazier, Ray Leonard, Evander Holyfield, Roberto Duran, Vitali Klitschko, and Wladimir Klitschko cannot be used in the Bare Knuckle mode.

EA is releasing the DLC on Xbox 360 worldwide March 29th. PS3 users can pick it up on March 29th in North America/Japan and on March 30th in Europe.
