Pokrajac was injured, forcing the promotion to scramble and add Mike Massenzio, who returns to the UFC after posting a 1-2 record in his first Octagon run. Massenzio typically fights at middleweight but will accommodate Soszynski at 205-pounds.
Light heavyweights Krzysztof Soszynski and Igor Pokrajac have been slated to square off against each other at UFC 140 on Dec. 10 in Toronto, Ontario, Canada.
