Gennadiy Golovkin, who won a vacant middleweight world title on Oct. 5 in New York, and mandatory challenger Kamil Szeremeta, who won on the undercard, have agreed to terms to meet in late February or March, a source with knowledge of the deal told ESPN on Thursday. Two weeks ago Matchroom Boxing promoter told ESPN the sides were in discussions and that the bout, if it were to be signed, could take place in Chicago, where Poland’s Szeremeta would be a draw from the city’s large Polish community.
