in an interview, Chisora claimed he offered Whyte £1.1 million for a rematch, which Whyte declined. 2017–2018 On 24 March 2017, it was announced that Chisora would get his much awaited rematch against Finnish boxer Robert Helenius (24–1, 15 KOs) at the Hartwall Arena in Helsinki, Finland. The same arena they fought at when Helenius won a controversial split decision in December 2011. The bout would be contested for the vacant WBC Silver heavyweight title on 27 May 2017. In December 2015, the EBU ordered for Chisora and Helenius to meet, where the winner would fight Anthony Joshua. A purse bid deadline was set for 21 January 2016, but no progress was made.

The fight was scheduled for 6 and ended in round 5 when the referee had seen enough, giving Chisora the win via TKO.
