Jake Paul has to strip down to his underwear as he weighs in for his fight against Nate Diaz as ‘The Problem Child’ weighs 185 pounds

Jake Paul weighed in at 185 pounds prior to his bout with UFC icon Nate Diaz in Dallas Saturday night.

Before the ceremonial weigh-in later today, Paul weighed ‘on the money’, as he put it on Twitter.

The catchweight was set at 185 pounds for the boxing fight – the first of Diaz’s career. Paul had to undress to make sure he met the weight.

Diaz weighed in following Paul and came in 0.1 pounds lighter at 184.9 – making sure everything goes as it should for tomorrow’s fight.

The pre-fight press conference on Thursday turned into chaos as Paul and Diaz faced off in Dallas with a huge brawl between the two rivals’ staff.

It’s unclear what prompted the scuffle, but Diaz appeared to exchange words with Paul’s manager Nakisa Bidarian on stage at the American Airlines Center.

Security for the YouTube star turned boxer intervened and crept around the couple, before one member of staff shoved another, leading to an all-out brawl.

Punches were thrown, but both boxers managed to stay away, with Paul even turning his back to the fight and shouting something to the crowd.

On Saturday, Diaz will see a foot in the boxing ring for the first time. The former UFC star defeated Tony Ferguson on his last MMA outing at UFC 279 last year.

‘The Problem Child’ enters the fray after the first loss of his short pro career, losing to Tommy Fury in Saudi Arabia in February.
