Former UFC lightweight champion Sean Sherk will face off against Rafaello Oliveira at UFC 108 on Jan. 2 in Las Vegas.

UFC 108 is scheduled for the MGM Grand Garden Arena and features Cain Velasquez vs. Antonio Rodrigo Nogueira and Rashad Evans vs. Thiago Silva as headliners.

Sherk (33-4-1) made the announcement Friday via Wisconsin Combat Sports.

Sherk, 36, told the website he plans to stay in the game until he turns 40 and reaches 50 fights.

The Minnesotan has struggled since returning to the Octagon after a one-year suspension due to alleged steroid use, going 1-2 against the division’s top-tier fighters.

Most recently, Sherk dropped a unanimous decision loss to Frankie Edgar at UFC 98, prompting a post-fight dash from the arena that raised many eyebrows. Sherk told the website he had no desire to rematch Edgar and preferred do-overs with champion BJ Penn and Kenny Florian in addition to current challenger Diego Sanchez.

Oliveira (11-2) fell short in his Octagon debut at UFC 103, losing a unanimous decision to Nik Lentz which snapped a three-fight win streak.
