This coming June will see a bout that should have happened seven years ago under the Elite XC banner as MMA legend Ken Shamrock faces Kimbo Slice at Bellator: Unfinished Business. Shamrock will be returning to action after a four-plus year layoff, last competing in a losing effort to Mike Bourke at King Of The Cage: Platinum. Slice will also be returning to action after a four year absence, but he did compete multiple times as a boxer during his hiatus. Bellator: Unfinished Business takes place on June 20th from the Scottrade Center in St. Louis, Missouri with the aforementioned fighters headlining.
