Monte Cox's Adrenaline MMA organization returns for its fourth show on Sept. 18 with a headline fight between former UFC champion Tim Sylvia (24-6) and Jason Riley (6-1).

Riley, an Ohio-based heavyweight, confirmed the fight via MySpace, though the organization has not officially announced the "Adrenaline MMA IV" event.

According a report earlier this month from The Northwest Times of Indiana, Adrenaline MMA IV takes place Sept. 18 (a day before UFC 103 in Dallas) at the Mid-America Center near Omaha, Neb., in Coucil Bluffs, Iowa, and is also likely to feature Jeremy Horn (81-19-5).

The report also stated UFC light heavyweight Houston Alexander (8-4) is expected to compete on the card. MMAjunkie.com (www.mmajunkie.com) spoke to a source close to the fighter and confirmed Alexander has agreed to fight on the card after receiving permission from the UFC to take an outside bout. Alexander, a popular fighter who's unfortunately suffered three straight losses, expects to return to the UFC later this year if victorious.

I'm actually excited for this card just because its going down about 2 hours from my house, so I can actually go to it. Should be able to get a few autographs at the event, and decent seats pretty cheap.
