Randleman had to bow out due to a torn labrum in his left shoulder. He had suffered the injury prior to his return to Japan at "Sengoku 2" on May 18, but the shoulder worsened when he threw his first punch in the fight. Randleman would grind out the unanimous decision against Pancrase 2006 Neo-Blood tournament champion Ryo Kawamura.
Rodriguez (28-9), who defeated Randy Couture at UFC 39, last fought on April 11 in the single-night heavyweight tournament promoted by YAMMA Pit Fighting, the new organization from UFC co-founder Bob Meyrowitz. Rodriguez lost a one-round decision to eventual winner Travis Wiuff.
Monson (24-8) competed in the main event on the same "Sengoku" card with Randleman, losing to Josh Barnett by unanimous decision. Monson is taking a risk by taking a fight against Mike Russow for Adrenaline MMA a week before this fight against Rodriguez. Both debuting promotions are counting on the grappling champion as the headliner.
