Beterbiev represented Russia at the 2008 and 2012 Olympics and moved to Montreal to begin his pro career in 2013. Nearly eight years after turning pro, he will fight in Russia for the first time, and for the first time since unifying world titles in October 2019 with a scintillating 10th-round knockout over Oleksandr Gvozdyk. Deines, who turns 30 on Feb. 8, has won a pair of bouts via stoppage since the lone loss of his career, a June 2019 unanimous decision to Meng Fanlong in Macau, China.

Ramirez (26-0, 17 KOs) has been a world champion since March 2018, when he toppled Amir Imam via unanimous decision to win the vacant WBC strap. Following the Imam victory, he hired noted trainer Robert Garcia, and the duo has combined to go 4-0 in world title fights. Ramirez knocked out Maurice Hooker in July 2019 to unify world titles and defended his belts last August with a majority decision over former world champion Viktor Postol. Taylor toppled Postol by unanimous decision in 2018 and won the IBF world title the following year with a decision over Ivan Baranchyk. He unified the IBF and WBA titles in October 2019, edging Regis Prograis by majority decision in a brutal masterpiece. He made his first defense as a unified champion last September, blasting out mandatory challenger Apinun Khongsong in the first round.
