Frank Shamrock vs Ken ShamrockIt’s been talked about for as long as I can remember. Now, it’s signed. Brothers, Frank and Ken Shamrock, have agreed to fight each other in 2009. Michael Woods of has the report.

“We’ve both signed a contract to fight each other,” younger brother Frank Shamrock told “Ken is down with it. We talked about it two years ago, and we’ve agreed materially to fight.”

“Will the fight happen? Absolutely,” Ken Shamrock told “He’s got a buttkicking coming to him. Everything I’ve learned, everything I have bottled up in me, is going to come out on him. I’ve still got love for Frank, but I’m angry at him.”

While the event will air on pay-per-view, the rest of the details have yet to be ironed out. The fight will likely take place in April, but as of right now, it is uncertain which promotion will actually host the fight. EliteXC and Strikeforce would seem to be the obvious choices considering the brothers’ ties to those organizations, however, after Ken’s Oct. 4 debacle with EliteXC & CBS, Strikeforce may become the more likely candidate.

In a report at Five Oz., CBS apparently wants nothing to do with Ken Shamrock ever again.

However, a source close to CBS speaking on the condition of anonymity informed that the network had no interest in ever promoting a bout involving Ken Shamrock again.

EliteXC’s future is clearly uncertain. A potential sale to CBS and/or Showtime seems to be best chance for the promotion’s survival. If that’s what happens, the Shamrock brothers will probably need to look elsewhere.

Shamrock vs. Shamrock certainly makes for an unique storyline, one that Jeremy Lappen likened to “Cain versus Abel,” but is it too late in Ken’s career for people to care? Whatever patience fans seemed to have left for Ken went out the window last weekend when cut himself and pulled out of the Kimbo fight at the last-minute.

I can see it drawing interest if it was aired on free television, but how many are willing to pay for it?
