The vacant IBF world super middleweight title will be determined this weekend when William Scull takes on Vladimir Shishkin in Germany. Scull was the IBF mandatory challenger for Saul "Canelo" Alvarez, who held all four major championships from November 2021 until May 2024. Faced with multiple madnatory defenses, Alvarez decided to vacate the IBF belt in order to face WBA mandatory Edgar Berlanga. That set up Saturday's fight between Scull and IBF #2 contender Shishkin. Both men are undefeated and each will fight for a world title for the first time in what could be a career-defining bout for one of these fighters. DAZN will air Scull vs. Shishkin on Saturday, October 19th at 8 p.m. UK / 3 p.m. ET.
