Heavyweight champion Randy Couture will
defend against top contender Josh Barnett in the main event on the Ultimate
Fighting Championship fight card this ÂÃ‚ÂFriday at the MGM Grand Garden Arena.
The event, billed as “Worlds
Collide,” pits Couture (7-2-0 in Mixed Martial Arts) of Gresham, Ore., against
Barnett (26-1) of Seattle. The bout will moved up to main event status when UFC
light-heavyweight champ Tito Ortiz suffered a torn ACL in his left knee and was
forced to cancel his title match with Vitor Belfort.
Couture, known as The Natural, has held
the heavyweight title longer than anyone and is still undefeated in the Octagon.
In the co-feature UFC welterweight
titlist Matt Hughes (25-3) will defend his crown for the first time against
top-ranked Hayato Sakurai (16-1-2) of Japan.
