World heavyweight champion Anthony Joshua will defend his IBF, WBA, WBO and IBO titles against Kubrat Pulev on 12 December at The O2 in London.
Joshua, 31, last fought in December 2019 when he reclaimed his titles from Andy Ruiz Jr with a unanimous points victory in Saudi Arabia.
Pulev was due to face Joshua in June but it was postponed because of the coronavirus pandemic.
It is not clear if it will be without fans because of Covid-19 restrictions.
