What happened: Veteran referee 'Big' John McCarthy weighed in on the disputed back-of-the-head strikes in the Ciryl Gane versus Alex Pereira fight. After repeated reviews, McCarthy said a couple of the blows did appear to land illegally. His assessment lends an authoritative voice to one of the bout's most contested moments.

Why it matters: Back-of-the-head strikes are among the hardest calls in MMA officiating, and a former referee publicly siding with the illegal-contact reading sharpens the scrutiny on how the sequence was handled. The debate carries weight for Alex Pereira as he maps out his next steps, and for how similar exchanges get officiated going forward.

What to watch: Watch for any further response from the fighters' camps or a more detailed breakdown of the flagged exchanges in McCarthy's full segment.
