The promotion confirmed on Saturday night that Sergey Spivak will step in for Sergei Pavlovich and meet Tom Aspinall on Sept. 4 at the UFC Apex in Las Vegas. According to a report from MMAjunkie.com, Pavlovich was forced out of the card due to visa issues. UFC Fight Night 191 is headlined by a middleweight showdown between Derek Brunson and Darren Till.
Spivak has built some momentum since a loss to Marcin Tybura at UFC Fight Night 169, as he has won his last three promotional appearances. Most recently, “The Polar Bear” outpointed Alexey Oleynik at UFC on ESPN 25.
Aspinall, meanwhile, is on a six-bout winning streak that includes finishes of Jake Collier, Alan Baudot and Andrei Arlovski in UFC competition.
