Stevenson vs Fonfara undercard: Lemieux to face Guerrero, Beterbiev takes on Jeff Lacy, more

Adonis Stevenson headlines again at Montreal's Bell Centre on May 24, facing Andrzej Fonfara in the main event on Showtime, defending his WBC and Ring Magazine light heavyweight championships. The undercard is now coming together, as well.

In the main prelim bout, middleweight puncher David Lemieux (31-2, 29 KO) will face Fernando Guerrero (26-2, 19 KO) in a 10-round bout for the vacant NABF belt. Lemieux, 25, has won six straight since back-to-back losses to Marco Antonio Rubio and Joachim Alcine in 2011, and remains as fun to watch as he's ever been. Guerrero, 27, beat Raymond Gatica in his last fight, which came in November, about seven months after he was demolished against WBO titlist Peter Quillin.

The card will also see the return of Jeff Lacy (26-4, 18 KO), as the 36-year-old veteran will face Russian Olympian Artur Beterbiev (4-0, 4 KO) in a 10-round bout. Beterbiev, 29, competed in Beijing as a light heavyweight and in London as a heavyweight (201 lbs), and has fought professionally around 185 pounds, with the idea being to get him down to 175 if possible. Beterbiev won gold at the European Amateur Championships in 2006 and 2010, as well as the 2011 Worlds, where he also won silver in 2007. Lacy last fought in November, winning a TKO-3 over Martin Verdin, but that was his first fight since a 2010 loss to Dhafir Smith.

Also in action: Light heavyweight Eleider Alvarez (14-0, 8 KO) will likely face Radivoje Kalajdzic (15-0, 10 KO); welterweight prospect Mikael Zewski (23-0, 18 KO) will face Prince Doku Jr (18-5, 12 KO) in a 10-round bout; and Kevin Bizier (21-1, 14 KO), Oscar Rivas (13-0, 8 KO), Erik Bazinyan (3-0, 3 KO), and Yves Ulysse Jr (1-0, 1 KO) will also be on the bill.
