Showtime this week announced that on Saturday, March 8, it will present a combat sports double-header as part of its coverage of Cage Rage 25.

The evening begins at 9 p.m. ET/PT with live world championship boxing followed by Cage Rage, which is owned by Showtime partner EliteXC. Both events will take place in London and air back-to-back on Showtime.

The first event will air from the O2 Arena in London and will feature a World Boxing Organization cruiserweight championship fight between British boxers Enzo Maccarinelli and David Hayes.

The second show of the night will feature the return of Ken Shamrock to competitive mixed martial arts, as he faces Robert “Buzz” Berry in a heavyweight showdown as a part of the EliteXC owned Cage Rage event at Wembley Arena.

“I’m totally committed to getting back into the cage injury free and anxious about fighting in England and on Showtime for the first time,” Shamrock said. “Fight fans in England are a special breed and they are going to be treated to a very special show. Give me a fight or two and I will be ready to fight anybody.”

The Cage Rage event on Showtime will also feature bouts between featherweights Jean Silva and Masakazu Imanari, heavyweights Gary Turner versus Mustapha Al-Turk, and a middleweight bout between Pierre Guillet and Tom Watson.

Shamrock’s son Ryan will also be featured on a non-televised fight on the same Cage Rage card.

“It is very exciting for both Ryan and me,” the older Shamrock said. “We will be making MMA history by being the first father and son to ever fight on the same card. This is a great opportunity we are getting with EliteXC and Showtime.”
