Walt Harris (13-8) is a veteran of the UFC since 2014 and needs a big win on Saturday, as a victory could propel him to just outside the top five of the heavyweight division. The Big Ticket cashes in his victories by way of knockout, with all 13 of his career wins coming by the knockout. DraftKings has Harris as the underdog against Alexander Volkov with a salary of $7,600 for Saturday's main-card bout. Throughout his extensive UFC career, Harris averages 55.8 points per contest. On a need scale, this is massive for Harris, and he may just be able to pull out the upset to earn lucky No. 14 knockout in his career.
