Alexander Volkov and Jairzinho Rozenstruik have grown accustomed to working within narrow margins in a division where one mistake can result in awakening to a doctor shining a light in your face.

The two Ultimate Fighting Championship contenders are set to lock horns in the UFC Fight Night 207 headliner on Saturday at the UFC Apex in Las Vegas, where they will attempt to keep pace with the men ahead of them in the heavyweight pecking order. Volkov has lost two of his past three bouts. The former Bellator MMA and M-1 Global champion last appeared at UFC Fight Night 204, where he submitted to a straight armbar from Tom Aspinall in the first round of their March 19 pairing. Rozenstruik, meanwhile, has alternated wins and losses in each of his past five outings. He last competed on Sept. 25, when he dropped a unanimous decision to Curtis Blaydes in their three-round encounter at UFC 266.
