What happened: At the UFC London ceremonial weigh-ins, tension escalated as Brazilian Luana Carolina weighed in 8 pounds over the bantamweight limit at 138lbs, opposite UK fighter Melissa Mullins who hit 135lbs exactly and broke down in tears. The fight was scrapped, marking the only miss reported. All main card fighters, including featherweight title eliminator headliners Movsar Evloev and Lerone Murphy, made weight.

Why it matters: The cancellation disrupts prelim with automatic refunds but eliminates props and parlays involving the bout, frustrating. It underscores weight management challenges in MMA, potentially impacting Carolina's future bookings and UFC payouts for Mullins. Hype builds for the unmarred main card tomorrow.
