Middleweight champ Gennadiy Golovkin to fight Kamil Szeremeta on Dec. 18

GGG is back.

IBF middleweight champion Gennadiy Golovkin will meet mandatory challenger Kamil Szeremeta on Dec. 18 at the Seminole Hard Rock Hotel & Casino in Hollywood, Florida, DAZN announced Tuesday.

The bout was initially scheduled for February and then April, with the latter date scrapped due to the COVID-19 pandemic.

The Golovkin-Szeremeta fight will take place one day before Saul "Canelo" Alvarez's matchup against Callum Smith. If Golovkin and Alvarez win their respective bouts, it could set up a trilogy battle between the two stars in 2021.

Golovkin (40-1-1) has not fought since a close, unanimous-decision win over Sergiy Derevyanchenko to win the IBF and IBO middleweight titles on Oct. 5, 2019. Golovkin, a 38-year-old native of Kazakhstan, has just two blemishes on his record -- a close loss and a draw against Alvarez.

This will be Golovkin's third fight as part of a three-year, six-fight deal with DAZN that is worth nine figures.

Szeremeta (21-0) fought on that GGG-Derevyanchenko card in 2019, beating Oscar Cortes via second-round TKO. This will be the biggest fight thus far for the 31-year-old native of Poland.
