Light heavyweights Gegard Mousasi and Jake O'Brien have agreed to meet at DREAM.15, which takes place July 10 from the Saitama Super Arena in Saitama, Japan.
MMA Fighting learned of the match up yesterday.
Mousasi is of course coming off the somewhat surprising defeat at the hands, (and takedowns) of King Mo Lawal back in April on CBS.
Before that loss, the 24-year-old fighter had been on a 15-fight tear, which dated back to 2006. He was nothing short of outstanding since coming out of seemingly nowhere to win the 2008 DREAM Grand Prix Final with an upkick stoppage of Ronaldo "Jacare" Souza.
"Dream Catcher" later went on to stop Renato "Babalu" Sobral to capture the Strikeforce light heavyweight crown and then tooled Rameau Thierry Sokoudjou via second round technical knockout three months later in a non-title bout.
Mousasi's last win came as he overwhelmed an under matched Gary Goodridge at K-1 Dynamite!!: "Power of Courage" on New Year's Eve 2009.
O'Brien has found success in the local MMA promotion circuit going 2-0 since being cut buy the UFC following his loss to Jon Jones at UFC 100 last July.
The veteran of 17 professional fights, having won 14 of them, entered the Octagon with an undefeated mark of 7-0 and carried his streak all the way to ten consecutive wins, culminating with a defeat of Heath Herring at UFC Fight Night 8 back in 2007.
Jake's only three losses came to Andrei Arlovski, Cain Velasquez, and Jon Jones... some pretty steep competition. And at just 25 years of age, O"Brien has plenty of time to work his way toward the top of the light heavyweight ranks.
