Ex-Jackson Wink GM reveals Howkit sparring details, Jones memory lapses, and gym's decline

June 7, 2026

Quick read

Former Jackson Wink general manager Mikhail Lyubimov shared a series of revelations about the renowned gym, including that Josh Howkit's primary sparring partner is a welterweight grappler with a losing record and that Greg Jackson will not be in Howkit's corner at UFC White House for personal political reasons. Lyubimov also revealed that Jon Jones could not recall sparring with Jiri Prochazka, Vagab Vagabov, or Modesta Bukauskas, and that Jones once forced Roman Dolidze out of the gym after Dolidze was consistently troubling him and the coaching staff on the mat. He attributed Jackson Wink's decline to burnout from both Greg Jackson and Mike Winkeljohn, with Winkeljohn increasingly focused on real estate. Additional notes covered Cub Swanson's departure after Arman Ospanov broke his ribs with a spinning kick in sparring, and Claressa Shields' struggles in MMA being attributed to her refusal to engage seriously in wrestling and grappling.
