Undefeated American Top Team (ATT) heavyweight Todd Duffee (4-0) will finally make his much anticipated Octagon debut when he faces one-fight Pride FC veteran Mike Russow (11-1) at UFC 102.

The promotion today made the long-rumored match official, completing the fight card for the first-ever event for promotion in "The City of Roses," which is scheduled for The Rose Garden in Portland, Oregon on Saturday, Aug. 29, 2009.

Duffee was supposed to crack into the big leagues against Mustapha Al Turk at UFC 99: "The Comeback" from the Lanxess Arena in Cologne, Germany, on June 13. However, he was replaced with Mirko Cro Cop just a few weeks out from fight night.

Cro Cop went on to score a first round technical knockout of the former British Cage Rage heavyweight champion with the help of an inadvertent eye poke and that went unnoticed by the referee in charge of the action.

Duffee is coming off an impressive second round technical knockout of Brazilian roadblock Assuerio Silva at Jungle Fight 11 last September. The 20-something University of Georgia student has ended all four of his professional fights by way of (technical) knockout.

Russow has racked up a solid mixed martial arts record (11-1), while also protecting the fine citizens of the "Windy City" as a Chicago police officer. His only defeat came by way of submission to Sergei Kharitonov back at Pride 33 in February 2007.

The loss didn’t do much to faze the former high school state champion wrestler, who’s been perfect (7-0) ever since, compiling wins over names like Steve Campbell and Roman Zentsov.

In addition to his five-o gig in Englewood community in Chicago’s 7th district, Russow is a longtime student of former UFC welterweight champion Matt Hughes, whom he trained under as a wrestler at Eastern Illinois University.
