Islam Makhachev has officially vacated his lightweight title, with the 33-year old set to move to welterweight to challenge Jack Della Maddalena for the 170-pound title. Makhachev's decision to pursue a second belt has seen a potential mega-fight with Ilia Topuria be put on hold, much to the disappointment of fans. Some of those fans believe that the former lightweight champion has intentionally avoided a clash with 'El Matador'.One such person is Barstool Sports employee and MMA personality, @DoubleVodkaDon, who took aim at Makhachev during a recent podcast episode on @SpinninBackfist. His comments on the Dagestani fighter saw a fiery response from Ali Abdelaziz, the longtime manager of Makhachev.@DoubleVodkaDon said this:"Let's call this what [it is]. Islam's a duck, I'm gonna say it 'cause Jack won't....[Della Maddalena] just fought, you're gonna have to wait months for that fight to happen. You could do both... [Topuria's fight] is in, what is it, May? It's a month and a half. If [Makhachev] beats Topuria, just fight [Della Maddalena] probably on the same exact timeline."Abdelaziz came across the comments on X, and shared a heated reply, writing this:"This fat motherf**ker need to stop eating and go to the gym, he should not be watching any sport or talking about any sport he's not qualified."Catch Islam Makhachev's manager respond to @DoubleVodkaDon below:Islam Makhachev and Ilia Topuria get heated onlineIslam Makhachev's friend and part-time teammate, Belal Muhammad, lost the welterweight title to Jack Della Maddalena at UFC 315 on May 10.

You are nobody in LW division, just a big mouth from Spain with nice haircut. Go get one W, and we can talk boy."'El Matador' responded with this:"The difference between you and me is that I am a man and you are a coward. I speak and fight. you talk and hide.
