here's an article from www.sherdog.com
A dispute over money has apparently caused heavyweight Mirko Filipovic (Pictures) to remove himself from September 10's PRIDE Open-Weight Grand Prix semifinal versus Wanderlei Silva (Pictures) and thus the highly anticipated Final Four, Croatian newspaper Vecernji list reported Saturday.
Filipovic's main point of contention appears to be the $150,000 purse that goes to the victor of the tournament — which the Croat said is insufficient considering he will have to win two bouts in one night to become Grand Prix champion.
The explosive striker, best known for a missile-like left high kick, said that he will close down training camp on Monday and leave for vacation.
When asked for reaction, a representative for Dream Stage Entertainment, the parent company of the PRIDE Fighting Championship, told Sherdog.com that they are in contact with the Croatian star. However DSE declined to offer any comment beyond that.
Vecernji list also reported that "Cro Cop" has fielded a substantial offer from the World Fighting Alliance, an American promotion that held a pay-per-view card on July 22 in Los Angeles.
