Mark Vologdin in peak form for UFC debut against John Castaneda

Mark Vologdin, 25, is in excellent shape ahead of his UFC debut this weekend. Despite losing by decision on Dana White's Contender Series in October, both Vologdin and his opponent Adrian Luna Martinetti received contracts due to the exciting and brutal nature of their fight, which earned a standing ovation from Dana White. Vologdin holds a record of 12-4-1 with 6 knockouts and 4 submissions, represents Petrozavodsk in the Republic of Karelia, and is a master of sport in Kyokushin karate. He faces veteran John Castaneda, who has a 4-4 UFC record and last fought exactly one year ago, losing to Chris Gutierrez by split decision.
