Oleksandr Usyk sent a hilarious, but somewhat unsettling, video message to Derek Chisora on Saturday.
The former undisputed cruiserweight champion was due to face the Brit in his first test at heavyweight earlier this year, but the bout was of course postponed by the coronavirus pandemic.

Although no new date has yet been solidified for the fight, Eddie Hearn has mentioned October as a possibility.
As a result, both men are now back in training.
While out for a run at a Ukrainian beach on Saturday, Usyk decided to film a bizarre video reminding Chisora that he lies in wait.
“Derek,” a demented-looking Usyk shouted in broken English at the camera, “Derek, where are you Derek?

“I’m run. Derek, Derek!!
“Derek, I watch you run, time to run.
“Derek, how are you? Derek!”
The pair met for a first press conference in March, just before lockdown came into effect in the UK.

Back then, Usyk said of the fight: “Boxing in Manchester in 2018 [against Tony Bellew] was an amazing experience, now I get to do it in London at the famous O2 Arena and I can’t wait to fight in front of the British fans once again.
“As a cruiserweight, I reached the highest heights as undisputed champion and now I am following the same path as a heavyweight.
“I expect a real test in Chisora – he is strong, tough and resilient. I recall being an amateur and watching his fight with Vitali Klitschko. It seemed so big and far away.
“Now I am myself taking a fight against Chisora. I am working hard in my training camp to show a spectacular performance on May 23. Dear friends, I will see you soon!”
