What happened: Veteran referee John McCarthy criticized Dan Miragliotta for ordering a standup during the UFC Vegas 123 main event, stating, "That's not your job." The contested separation broke up grappling exchanges on the mat before Tom Nolan secured a third-round technical knockout.

Why it matters: The decision generated widespread debate among fighters and analysts over whether the referee intervened prematurely while Renato Moicano worked for control. Nolan capitalized on the restart moments later, stopping Moicano at 1:28 of the third frame to move to 12-1.

What to watch: Moicano and Nolan now await their next lightweight bookings following the UFC Vegas 123 outcome.
