Badou Jack won’t get his long-awaited rematch with Jean Pascal after all.

Jack announced Friday night on Twitter that Pascal tested positive for three steroids and has been removed from their light heavyweight championship rematch, which was scheduled for June 6. The second bout between Pascal and Jack was supposed to be Showtime Pay-Per-View’s co-feature before the Floyd Mayweather-Logan Paul exhibition at Hard Rock Stadium in Miami Gardens, Florida.

“My fight with @jeanpascalchamp is OFF as he tested positive for 3 different steroids,” Jack wrote on Twitter. “We suspected he was dirty the first time around and @Vada_testing confirmed it this time. I’m still fighting on June 6th and my team is looking for a replacement opponent. Alhamdulillah.”

Yahoo! Sports’ Kevin Iole reported minutes before Jack’s announcement that Pascal failed tests for three steroids – Drostanolone, Drostanolone Metabolite and Epitrenbolone.

Jack added in a subsequent Tweet, “Btw…this wasn’t the first time this happened to me. Lucian Bute took steroids for our fight & now Jean Pascal. Are you so scared of a fair fight with me that y’all need to take steroids to fight me? #Cowards @lucianbute @jeanpascalchamp.”

The bout between Pascal, 38, and Jack, 37, was widely viewed as the most competitive match among the four fights Showtime Pay-Per-View scheduled as part of the Mayweather-Paul telecast a week from Sunday night.

Quebec’s Pascal (35-6-1, 20 KOs, 1 NC) edged Jack by split decision in their 12-round fight in December 2019 at State Farm Arena in Atlanta. Pascal floored Jack in the fourth round and survived a 12th-round knockdown to defeat the Swedish-born, Las Vegas-based Jack on two of three scorecards (114-112, 114-112, 112-114).

Pascal won the WBA world 175-pound championship from Jack that night. Jack (23-3-3, 13 KOs), a former super middleweight and light heavyweight champion, is promoted by Mayweather’s company.

Pascal hasn’t boxed since he beat Jack almost 17 months ago. Jack most recently out-boxed Blake McKernan (13-1, 6 KOs) by unanimous decision in an eight-rounder November 28 at Staples Center in Los Angeles.
