The World Alliance of Mixed Martial Arts issued a press release on Thursday announcing that the heavyweight main event between Josh Barnett and Andrei Arlovski that is scheduled for Affliction’s “Day of Reckoning” pay-per-view on Oct. 11 will determine the number one contender to the WAMMA heavyweight title currently held by Fedor Emelianenko.

“We couldn’t be more excited to see Andrei Arlovski and Josh Barnett faceoff for the right to take on Fedor for the WAMMA World Heavyweight Championship,” WAMMA CEO Dave Szady is quoted as saying in company-issued a press release. “In the spirit of crowning undisputed champions, we couldn’t be happier than to have two of the fighters who arguably deserve a shot at Fedor fighting it out for the chance to take on the champ.”

Both fighters competed at Affliction’s first-ever event on July 19 and both were victorious, with Barnett recording a second round knockout over Pedro Rizzo and Arlovski knocking out Ben Rothwell in the third round.
