Phil Baroni has singed to face Murilo “Ninja” Rua as part of the first ever ElilteXC-CBS Saturday Night Fights show taking place in New Jersey on May 31, independent sources close to the fight have confirmed to MMAWeekly.com

Baroni is coming off of a tough loss to new ICON middleweight champion Kala Kolohe Hose, after a hard fought battle just over a week ago.

This will be Baroni’s second fight back following a six-month suspension stemming from a positive test result for a performance enhancing substance following his 2007 fight with Frank Shamrock.

Rua, a former EliteXC middleweight champion, lost his title to Robbie Lawler in September 2007, but rebounded with a win in Cage Rage over Xavier Foupa-Pokam in early December.

The middleweight bout will serve as part of the undercard to a main event featuring EliteXC heavyweight Kimbo Slice against an as of yet unnamed opponent. EliteXC has also announced a title bout between Lawler and Scott Smith as part of the May 31 fight card.
