Max Holloway has officially entered the welterweight division, stepping on the scale at 170lb for his first fight in the class at the T‑Mobile Arena in Las Vegas. The 34‑year‑old, who has 27 wins from 36 bouts, previously campaigned at featherweight and recently claimed the BMF title after defeating Dustin Poirier, before losing the belt to Charles Oliveira.

Conor McGregor, 37, returns after a long layoff, his last fight ending in a leg‑breaking defeat to Poirier in 2021. McGregor’s comeback has been marred by legal issues and missed drug tests, sparking debate over his place in the spotlight. He weighed a hair lighter than Holloway, and the two exchanged a tense staredown after McGregor pulled Holloway’s glasses off during the pre‑fight press conference.

The arena buzzed with mixed reactions, as fans cheered and booed Holloway in equal measure. The event also showcases other key contenders: Paddy Pimblett and Benoit Saint‑Denis at lightweight, and Kavanagh and Riley at flyweight, each eyeing a future title shot.

The fight’s outcome will set the tone for the rest of UFC 329, determining whether Holloway can sustain his momentum at a higher weight and whether McGregor can re‑establish_T‑Mobile Arena as a platform for elite competition.
