Tyson Fury vs Deontay Wilder 3: Fight rescheduled for October 9
"Make no mistake, I will be back and better than ever. We will fight (on) October 9 and I will knock him spark out."
On Friday, Planet Sport reported that Fury had contracted Covid-19 and it means another delay before he can put his WBC title on the line in a third meeting with Wilder.
Neither fighter has been in the ring since their 2020 clash, which saw Fury become WBC heavyweight champion in emphatic style.
ESPN+ pay-per-view and FOX Sports pay-per-view will broadcast the fight in America while the rights are yet to be confirmed in the UK.
Fury said: "I wanted nothing more than to smash the 'Big Dosser' on July 24, but I guess the beating will have to wait. Make no mistake, I will be back and better than ever. We will fight (on) October 9 and I will knock him spark out."
A court ruling in May forced Fury to ditch an immediate bout with Anthony Joshua and instead face his American rival again.
Fury first fought the 'Bronze Bomber' in December 2018, when a controversial draw verdict was recorded at the Staples Center.
