JAKE PAUL has been brutally warned that Mike Tyson is knocking out TEETH in sparring for their fight.
The heavyweight legend makes his return after TWO DECADES out the ring to face YouTuber-turned-boxer Paul on Friday in Texas.
He did take on fellow great Roy Jones Jr in a 2020 exhibition bout - and 6-1 cruiserweight Mike Russell was in Tyson's camp.
But almost half a decade on and Russell warned Iron Mike has shaken off even more rust.
He told SunSport: "I mean, he was already looking tremendous four years ago and now he's peaked higher than a peak.
"Mike is ready to go and Mike is gonna go out there and he's going to win spectacular."

Russell, 31, has only ever got two black eyes from boxing, one when he was a teenager and the other from Tyson, 58.
But he revealed there has been far more damage caused than just a shiner.
Russell said: "We have a young buck that's coming up right now, he did knock his tooth out but it wasn't me!
"But yeah, Mike did knock someone's tooth out in camp. He's doing great, man.

"He's gonna come out and he's gonna win and what he gonna win by knockout. I'm telling you right now."
Tyson returns for the first time as a professional since 2005 when he quit on his stool and threw the towel in on his career.
And he does so over eight two-minute rounds - opposed to the usual three - with bigger 14oz gloves on instead of 10oz.
But Russell insisted the rules change matters little as he doubts 10-1 Paul makes it into the third.
He said: "I think he's gonna finish the job within the first two rounds."
