I have no clue what his name is. All I know is he's a 6'8" basketball player and there's pics of him wearing not only the WOLF costume, but other generic AVP styled Predator costumes on the set of AVP-R. Good chance he's a stuntman and/or stand in for shots of Ian Whyte, who is still listed as playing WOLF in the movie. Hollywood uses stand-ins all the time. Maybe it's like the end of Predator 2, where Kevin Peter Hall was playing the elder, and there was another shorter guy in the "dead" hero P2 suit at the same time in the same shot. Maybe something like that happens here. Maybe Ian Whyte is playing an elder or something and there needed to be WOLF in the same scene at the same time. I don't know.
