#2. Walt Harris (11-7-0-1) vs. Sergey Spivak (9-0) (Heavyweight)

Walt 'The Big Ticket' Harris had a lot of naysayers in the build-up to the fight, after all, the decision of his last outing against Andrie Arlovski had to be overturned to a NC after he tested positive for LGD-4033.
His opponent, this time around though, wasn't a veteran, but an undefeated 24-year-old prospect. Sergey Spivak was another fighter who made his debut tonight, however, even he tasted the same fate as Marc-Andre Barriault did in the first bout of the main card.
