The match has not been officially confirmed yet, but it was first reported by the Brazilian TV channel Combate and also sources to SVT Sport confirm the information.
32-year-old Meerschaert is by far Chimaev's most deserving opponent to date.
In 2018, the American lost to the Swede Jack Hermansson in the first round.
Chimaev played two matches in ten days in July and won both convincingly.
