Kimbo Slice is set to headline EliteXC's first event in conjunction with CBS. The event will air on May 31 and will be featured on a prime time slot.

Gary Shaw recently revealed that Kimbo's opponent has been decided upon but won't revealed until tonight's EliteXC/Strikeforce show.

Dave Meltzer, of Yahoo!Sports.com, is reporting that 280-pound former UFC veteran Ron Waterman will probably be announced as Kimbo's opponent for the May 31 show.

The 42 year old Waterman is known primarily as a wrestler and could pose issues for Kimbo on the ground, as he would likely be reluctant to stand and trade, instead opting to go for takedowns and ground and pound due to his substantial wrestling pedigree.
