The hunt is on for a replacement opponent for the world's top heavyweight, Fedor Emelianenko after Josh Barnett, failed a pre-fight drugs test.

The CSAC denied former PRIDE star Barnett a license for his scheduled bout against Russian Emelianenko at Affliction: Trilogy on August 1 at the Honda Center in Anaheim, California after 'The Baby Faced Assassin' tested positive for a banned performance enhancer.

Rumoured replacements for the fight include Vitor Belfort, submission machine Jeff Monson, strikeforce's emerging heavyweight Brett Rogers and former WWE superstar Bobby Lashley.

The other big rumour coming out of UFC headquarters is that British star Michael Bisping and all-time great Wanderlei 'The Axe Murderer' Silva will meet at UFC 105 in Manchester on November 14.

Since re-joining the UFC in 2007, Silva has dropped decisions to former UFC champs Chuck Liddell and Rich 'Ace' Franklin, and was brutally knocked out by longtime foe Quinton 'Rampage' Jackson.

Silva's lone victory came in just 36 seconds against the notoriously hot-and-cold Keith Jardine.

The Bisping fight would be Silva's first at middleweight after a lengthy stint at 205 lbs.

Bisping dropped down to middleweight last year after suffering the first loss of his career to future 205lb champion Rashad Evans.

Since dropping to 185lb, Bisping reeled off easy victories over 'Chainsaw' Charles McCarthy, Jason Day, and Chris Leben but came unstuck at UFC 100, brutally knocked out by fomer PRIDE 185 and 205lb champion Dan Henderson.

The UFC 105 card is also expected to feature Nottingham's Dan 'The Outlaw' Hardy and The Ultimate Fighter 9 winners James Wilks, from Melton, and Ross Pearson.

Monday night saw the DREAM 10: Welter Weight Grand Prix 2009 Final Round take place at the Saitama Super Arena in Japan.

Despite not looking like a top-class card on paper, the event turned out to be one of the most entertaining of the year so far.

The main attraction was GP itself, which had Lithuanian striker Marius Zaromskis scooping the GP belt and DREAM's inaugral 170lb title by taking out Japanese hope Hayato Sakurai in the first semi via left high-kick and American Jason High, who had progressed by out-hustling Black House's André Galvão, by right high-kick in the final.

BJJ expert Shinya Aoki shocked the world by turning striker in his match against fellow grappling expert Vitor 'Shaolin' Ribeiro and taking a wide unanimous decision.

Former WEC middleweight champion Paulo Filho survived a brutal early flurry from Dutch kickboxer Melvin Manhoef to secure an armbar at the 2:36 mark of round one, while Team Quest's Tarec Saffiedine enjoyed a successful Dream debut, defeating Seichi Ikemoto by unanimous decision in the welterweight grand prix reserve bout.

Tough Korean Judoka Dong Sik Yoon broke his foot in the early moments of his fight with former TUF alumni Jesse Taylor.
