Amir Khan says Jake Paul is "very bad for boxing" but has warned that the YouTuber-turned-boxer is "going to hurt" Gervonta 'Tank' Davis in their upcoming exhibition bout.
Former world light-welterweight champion Khan told BBC Sport the huge size and weight difference between the pair makes the fight, which takes place on 14 November in Atlanta, a dangerous mismatch.
Paul, 28, will face undefeated 30-year-old lightweight world champion Davis, who has won 30 of his 31 fights, with 28 knockouts, in an exhibition that will not count towards either man's professional record.
"Jake Paul, in my opinion, is going to hurt Gervonta Davis," Briton Khan said. "Davis is a tiny little man compared to Paul. I think it's a big mismatch."
The weight disparity between the two fighters is stark - Paul weighed in at 200lbs for his last bout, while Davis campaigns at 135lbs.
There is also a significant height and reach difference, with 6ft 1in Paul standing eight inches taller and having a nine-inch reach advantage.
"It shows to me that Tank's acting desperate by taking a fight like that," Khan said.
"One day someone is going to get hurt so badly. No-one wants to mess about in the MMA cage but they're taking boxing so lightly and they're taking it as a joke."
