Roan Carneiro (Pictures) and Ryo Chonan (Pictures) have signed to fight at UFC 85 on June 7 in London, sources close to both camps have told Sherdog.com.

The bout will be a rematch of a Feb. 12, 2005, meeting in Deep. Chonan (14-8) stopped the Brazilian on a cut in that first fight after landing a knee as Carneiro (12-6) tried for a takedown.

Both fighters have since dropped from the middleweight division to 170 pounds.
