Once-beaten Kubrat Pulev has announced to his followers that everything has been finalized to fight IBF, IBO, WBA, WBO heavyweight world champion Anthony Joshua on December 12 in London.

The 39-year-old, who is the mandatory challenger under the IBF, had been scheduled to meet Joshua on June 20 but the fight was postponed due to the COVID-19 outbreak.

The fight date was kicked around a few more times, before settling down in the month of December.

“No turning back, no procrastination! Kubrat Pulev vs Anthony Joshua! The date is December 12th and the place is London! The date and place of the event are now final and not subject to change, and both parties have signed the official contract," Pulev stated.

For Joshua, 30-years-old, the bout will be his first since he won a twelve round unanimous decision over Andy Ruiz in a rematch in Saudi Arabia last December to avenge his first career defeat and reclaim his world titles.

The British superstar was initially scheduled to fight Pulev at Cardiff’s Principality Stadium in October 2017. The fight was called off when Pulev withdrew after suffering a shoulder injury in sparring.

Pulev suffered his only career defeat back in 2014, when he was knocked out in five rounds by Wladimir Klitschko in Hamburg.
