Kimbo Slice, Ken Shamrock set bout

More than six years after it was first scheduled to happen, Kimbo Slice and Ken Shamrock will share a mixed martial arts cage.

Bellator MMA officials have confirmed that a nontitle heavyweight fight between Slice (birth name Kevin Ferguson) and Shamrock will headline a Spike TV event on June 20 inside Scottrade Center in St. Louis.

The two were booked to headline an event promoted by now-defunct organization EliteXC on Oct. 4, 2008, in Sunrise, Florida. Shamrock withdrew from the fight the day of the event, however, citing an accidental cut suffered during prefight warm-ups.

In a release, Slice said, "Ken [Shamrock], I owe you this a-- whooping. No more running! No more hiding!"

Shamrock, 51, who has never officially retired but also has not fought since November 2010, confirmed he has signed a multifight deal with Bellator.

"I am back," Shamrock stated. "It's good to be performing again for my fans. I feel great and my health is great. Age should never be a factor if an athlete is healthy, in great shape and has the drive to continue their sport. I will quit fighting when I want to.

"Kimbo Slice and I have some unfinished business. I am a fighter. That's who I am."

After the initial matchup between the two fell through, Slice (4-2) went on to fight Seth Petruzelli in the EliteXC event, which aired on CBS. Petruzelli scored a shocking 14-second knockout, handing Slice his first professional MMA loss. The promotion ceased operations entirely later that year.

A former backyard brawler Internet sensation, Slice, 41, also has been away from MMA since 2010. The Miami native competed in seven professional boxing matches since his last MMA fight, however, compiling a 7-0 record with six knockouts.

Slice appeared as a contestant on the UFC's reality series "The Ultimate Fighter" in 2009. He lost in the first round to Roy Nelson via TKO. He went on to an official 1-1 record in the UFC. He suffered a TKO loss to Matt Mitrione at UFC 113 in May 2010, his last MMA fight.

A pioneer in the sport, Shamrock (28-15-2) made his professional debut in 1993. He suffered a now-infamous submission loss to Royce Gracie in the semifinals of the first-ever UFC tournament.

Now training out of San Diego, Shamrock won the UFC Superfight Championship (an open weight category) at UFC 6 in 1995. He is perhaps best known for a long-standing feud with former UFC light heavyweight champion Tito Ortiz, whom he fought three times between 2002 and 2006.

His third and final meeting against Ortiz at UFC Fight Night in October 2006 remains the most-watched MMA fight of all time on Spike TV, generating 6.5 million viewers.

In his last fight in 2010, Shamrock suffered a first-round knockout loss to Mike Bourke in South Africa when he was unable to continue due to a leg injury. Officially, it was the ninth knockout loss of his career.
