Walsh (15-0, 11 KO) has been heavily hyped by White for years, with several of Walsh's fights streamed on UFC Fight Pass. With TKO's expansion into the boxing world with the new promotion, Zuffa Boxing, Walsh seemed like a sure thing to have been an anchor for the new promotional body, and his headline spot confirms those suspicions.

Zuffa boxing will hold its first event later this month, headlined by undefeated Callum Walsh (15-0, 11 KOs) taking on veteran Carlos Ocampo (38-3, 26 KOs) in a junior middleweight fight at the UFC APEX on Jan. 23, the night before UFC 324. Dana White announced the news while speaking with Stephen A. Smith over the weekend.

The Meta Apex will host UFC and Zuffa boxing events, with tickets available to the public for the first time. Meta and UFC are expanding on the partnership they first struck last year, with the tech giant scoring naming rights to the UFC’s Las Vegas facility, which will be renamed the Meta Apex.
