People point out same concern as new rule is announced for Jake Paul fight vs Mike Tyson

Boxing fans are worried about a particular detail of the upcoming fight between Mike Tyson and Jake Paul.

No, it's not the fact that a 27-year-old is going to be fighting someone who will be 31 years his senior by the time they step into the ring, and who doctors have issued health warnings to.

Nor is it (this time at least) the announcement that this fight was going to have two minute rounds, with Tyson calling it 'an exhibition' but promising that viewers will be in for a proper fight.

In fact, despite what Tyson previously said, the fight has now been sanctioned as a professional bout, meaning it'll go on the boxer's professional records.

Jake Paul was an eight-year-old the last time Tyson fought a professional bout, the then-38-year-old picking up his sixth career loss to Kevin McBride in 2005.

This time, the thing people are worried about is the report from ESPN which says there will be no headgear worn by the boxers.

It's going to be up to eight rounds of two minutes each, but boxing fans are worried that the lack of headgear and the allowance for knockouts means someone is going to get their block knocked off.

In a fight between a 27-year-old and a 58-year-old your money would probably go on the younger man, but people reacting to the 'no headgear' rule are wondering if Paul is 'literally going to die in one hit'.

Tyson is the boxer who won his first 19 professional bouts by knockout, and a dozen of those in the first round.

Of course in those days he hadn't even turned 20 yet and when he steps into the ring with Paul it'll be the widest age gap ever seen in a professional boxing match, but plenty still remember what 'Iron Mike' could do in the ring.

Others have said this fight is 'not a joke anymore' after the rules were announced and guessed that 'Jake probably running this whole fight then'.

Social media has declared the YouTuber turned boxer 'cooked' and predicted Tyson to 'have a damn field day'.

"I'm very much looking forward to stepping into the ring with Jake Paul," Tyson previously said of his upcoming fight.

"He's grown significantly as a boxer over the years, so it will be a lot of fun to see what the will and ambition of a 'kid' can do with the experience and aptitude of a GOAT.

"Now I plan to finish him.”

That sounds ominous.

The fight will take place on 20 July and be streamed on Netflix.
