MMA Weekly first reported the matchup this morning, but MMA Fanhouse was quick to debunk the rumor, with Affliction vice president Tom Atencio confirming that the bout had been briefly considered but was scrapped due to Gomi’s unwillingness to move up from 155-pounds. According to Atencio the fight was “never even close” to finalized.

Gomi (30-5), the former PRIDE lightweight champion, was one of the top-ranked lightweights in the world prior to suffering losses to Nick Diaz (later overturned), Sergey Golyaev, and Satoru Kitaoka in three of five bouts before returning to Shooto in May with a second-round knockout of Takashi Nakakura. Cooper (9-4) is currently riding a six-fight win streak, including an IFL victory over Rory Markham as well as recent wins against Patrick Speight at Affliction’s January event and Joe Cronin at Call to Arms 1 in May.

Affliction: Trilogy takes place on August 1st at the Honda Center in Anaheim, California and is headlined by Fedor Emelianenko vs. Josh Barnett.
