Jake Paul appears to be training for a transition to MMA - with his recent training footage leaving fans worried. Check it out below.
YouTuber turned combat sports star Paul is currently 5-0 in boxing after knocking out Tyron Woodley last month.
He's discussed a switch to MMA in the past and a recent feud with UFC president Dana White saw him offer to step inside the Octagon.
Now, the 24-year-old has uploaded footage of him training low kicks in the gym with the view to a potential fight.
He posted to Twitter: "1st day training kicks. Doubted every step of the way.. but kick down the doors of the doubters."
In the tweet he also tagged Bellator and PFL, two of the biggest promotions in America.
He didn't tag the UFC however and White is adamant he'll never work with Paul in a professional capacity.
Paul thinks he could be a success in MMA and he has an accomplished high school wrestling background.
'The Problem Child' said prior to his second fight with Woodley: "I don't see why if I can do boxing at this high of a level that I couldn't do MMA at this high of a level.
"I'm gonna go get coached up by Jav Mendez, Team Khabib [Nurmagomedov]. That's that. They're down -- 100 percent."
Fans have reacted to the footage and they're unsure on his technique right now.
One commented: "This is a different game."
Another said: "Lmao can barely hear that kick."
While a third put: "I could see that kick coming!"
Paul was set to fight longtime Tommy Fury last month before he had to pull out with a rib injury and bacterial chest infection.
Fury is desperate to reschedule the fight but Paul claims he's ready to move on.
He's even claimed he'd rather fight Tommy's brother, WBC world champion Tyson, or father John right now.
Paul told TheVolumeSport: "He wants the payday. But I said it before, I don't wanna take the fight with him, he doesn't deserve it.
"I'd rather fight Tyson Fury. I'll fight his brother or his dad before I'll fight Tommy."
Earlier this week saw Paul's steroid tests from his clash with Woodley leak online following White's latest bet.
He told Paul that he'd like to drug test him for two years and he'd happily be tested for cocaine for 10 if he was allowed to.
However, Paul and Woodley tested negative for any banned substances ahead of their bout in Florida.
