LAS VEGAS – Youssef Zalal has made the bold accusation that Calvin Kattar intentionally greased up prior to their UFC Fight Night 251 co-main event clash. Zalal (17-5-1 MMA, 7-3-1 UFC) earned his fourth consecutive victory since returning to the UFC for a second stint, and his biggest career win to date, with a unanimous decision triumph over Kattar (23-9 MMA, 7-7 UFC) on Saturday at the UFC Apex. He clearly won the first and second round before his opponent took the third, but there was a curious takeaway from the contest.
