Renato Moicano and Tom Nolan headline UFC Vegas 123 on Saturday night at the Meta APEX in Las Vegas, a lightweight clash that pits one of the division's most established names against one of its fastest risers.

The event, also billed as UFC Fight Night 292, follows a familiar script: Nolan, climbing the lightweight ladder, gets his toughest test yet against Moicano, a longtime contender who has served as the division's measuring stick for years. A win over the Brazilian veteran would be the kind of result that vaults a prospect into ranked territory; for Moicano, turning Nolan away would reaffirm his standing near the top of a crowded weight class.

Preliminary action opens the card before the main portion of the evening, with Sherdog's live coverage set to begin at 5 p.m. ET. The matchup carries classic stakes for a Fight Night headliner — experience and championship-level seasoning on one side, momentum and youth on the other — and the lightweight division rarely lets those questions go unanswered for long.
