Headlined by a heavyweight match between Ken Shamrock and Robert “Buzz” Berry — which may very well decide who gets the next shot at Kimbo Slice — Cage Rage 25 goes down tomorrow night at London’s Wembley Arena. Showtime will run a tape-delayed broadcast of the four top-billed fights at 10:30 p.m. ET. Those other three main card fights are:

Jean Silva vs. Masakazu Imanari (for the Cage Rage Featherweight World Title)
Neil Grove vs. Rob Broughton (heavyweights)
Pierre Guillet vs. Tom “Kong” Watson (middleweights)

Other matches on the 11-fight card include Ken’s son Ryan facing off against Georgio Andrews in a bantamweight match, a heavyweight throwdown between Mustapha al Turk and Gary Turner, and Cage Rage’s first female fight between Aisling Daly and the rather-fetching Aysen Berik. Some other things to be aware of:

— If you clicked that last link, you’d know that Aysen Berik is the sister of Cage Rage vet Sami Berik, who, despite his terrible 12-24 record, knocked Mark Smith out in 9 seconds in a Cage Rage Contenders fight in February.

— Betting odds have Ken Shamrock as a -240 favorite (encouraging for someone who’s won only one fight since 2001). Grove and Broughton are dead even at -115.

— Robert Berry is the lightest he’s ever been for a fight, but will still be coming in 20 pounds heavier than Shamrock.

— Neil Grove and Rob Broughton both hold wins over Robert Berry. Illness forced Berry to throw in the towel after the first round of his fight with Grove in December. Berry’s September 2006 match against Broughton fight ended in a first-round KO.
