Less than a week after seeing originally scheduled opponent Aleksei Oleinik moved as a replacement to fight Alistair Overeem in the UFC St. Petersburg main event, Harris will now fight unbeaten newcomer Sergey Spivak at UFC Ottawa on May 4.
Harris (11-7, 1 NC) is looking to get 2019 off on the right foot after his last outing, a split-decision win over Andrei Arlovski in December, was overturned to a no-contest due to Harris testing positive for a prohibited substance. Excluding that bout, he is 3-2 in his last five fights.
