Surging UFC heavyweight contender Ciryl Gane is the betting favorite for his upcoming UFC Vegas 30 headliner against Alexander Volkov.Gane is currently on a five-fight winning streak in the UFC and is undefeated in his professional career.UFC commentator Jon Anik shared the betting odds courtesy of DKSportsbook, which suggests Gane is likely to extend his winning streak at UFC Vegas 30.Across his UFC career so far, Ciryl Gane has beaten some big names including Tanner Boser, Junior dos Santos and, most recently, Jairzinho Rozenstruik.Although he failed to get a finish against Rozenstruik, another win against a top contender like Volkov is bound to capture Dana White's attention.The job at hand, however, is not an easy one for Gane. Volkov is known for his striking prowess and the Frenchman must be wary of his hands while entering his hitting range.Also read: KSI teams up with Wasserman Boxing to launch his own boxing promotional companyPoll question for today's @AnikFlorianPod: Who wins this Saturday's heavyweight main event?
