Undefeated American Top Team (ATT) heavyweight Todd Duffee (4-0) will make his much anticipated debut inside the Octagon when he faces UFC sophomore Mustapha Al Turk (6-4) at UFC 99 from the Lanxess Arena in Cologne, Germany on June 13 according to InTheGuard.TV.

Duffee is coming off an impressive second round TKO of Brazilian roadblock Assuerio Silva at Jungle Fight 11 last September. The 23-year old University of Georgia student has ended all four of his professional fights by way of (T)KO.

Al Turk — who fights out of the famous London Shoot gym in the United Kingdom — came up short in his debut against Cheick Kongo at UFC 92 after a successful run in Europe on the Cage Rage circuit. In fact, he has six wins in seven attempts for the promotion and was riding a two-fight win streak before getting dismantled at "The Ultimate 2008".

He is a pretty well-rounded fighter with serviceable boxing and solid grappling skills -– good enough to earn him the British Cage Rage heavyweight title.

UFC 99 is expected to be headlined by former middleweight champion Rich "Ace" Franklin taking on ex-PRIDE smashing machine Wanderlei Silva in his middleweight debut. Heath Herring and Cain Velasquez as well as Mike Swick and Ben Saunders are also expected to hook 'em up.
