Fans have questioned Logan Paul's boxing technique after a video emerged on social media of him only appearing to use his left hand.
The YouTube star is consindering a return to the ring for the first time since facing boxing legend Floyd Mayweather last June.
He previously accepted a bout with Brazilian comedian Whindersson - full name Whindersson Nunes Batista- after being challenged on social media.
A video emerged of Paul's return to training which has left fans questioning his lack of right hand punches, with one fan commenting: "To this day he still refuses to throw the right hand."
Another agreed: "His right hand is still not working."
One fan joked: "Bro, he has to be southpaw at this point."
A fan also questioned his movement: "How do you box for more than three years, fight Mayweather and still have zero hip movement."
Another fan compared Logan's technique to his brother Jake: "Logan Paul the athlete not the fighter, Jake Paul is the real fighter (no exhibition bull****. Logan is punching the bag for cardio, I doubt he can even beat/KO the likes of Austin McBroom or FazeSensei."
A fan agreed by continuing to mock his technique: "Logan Paul is practicing left hand and hugging."
Paul previously hinted at a ring return with former two-time rival KSI.
However the excitement was short-lived after he instead announced a new energy drink venture.
The 26-year-old later claimed with his former rival that they had retired from the sport of boxing to focus on other aspects of their careers.
However Paul was challenged on social media to which Paul replied, "Challenge accepted." Whindersson later replied: "Let's do it".

The Brazilian star recently fought former world champion Acelino Freitas which ended in a draw after Whindersson suffered a horror cut early on in the fight.
He is famous for his YouTube videos which are comedy-based and have helped him amass an Instagram following of 57 million, almost double Paul's following.
Whindersson's remarkable weight loss has been a huge factor as he looks to fight in boxing exhibitions having lost around 32kg to prepare for his ring exploits.
Paul has since confirmed his plans to face the Brazilian in addition to stating his plans to make a ring return.
"Yeah, I will," the 26-year-old told TMZ. "There's this Brazilian guy, his name is Whindersson, who I've got my eyes on."
Paul is yet to win a boxing match in three attempts having drawn with KSI before losing on a split decision.
