Former world heavyweight champion Tyson Fury left a short message to his fans on social media.
"Back on top on December 21," Fury wrote on social media.
On December 21, Fury will have to hold a rematch with Oleksandr Usyk, to whom he lost by split decision of judges on May 18 this year.
Earlier, Tyson said that it will be a while before he appears in training camp and starts preparing for the fight with Usyk.
