Is there any boxer who started after the age of 23?

Rocky Marciano and Jess Willard, just to name two ~

 

Dwight Muhammad Qawi started at age 25 with little amateur experience.
Bernard Hopkins made his first pro debut at age 23.

 

Besides what people have already said

Ken Norton (23)
Joe Joyce (24)

 

Nate Campbell started later and didn't turn pro until he was like 27 or 28

 

Tons. Hasim Rahman for one. Jameel McCline for another.

 

Lucas Browne started age 30 and won the WBA regular at HW

 

Are we also counting boxers that already have an extensive amateur background when they made their pro debut?

Lomachenko - age 25
Rigondeaux - age 28
Usyk - age 26

 

Ron Lyle started at 30 and had a chance to fight the world champion.

 

Lucas Browne alway came across as a gentleman to me. Big scary looking dude but I bet he wouldn't hurt a fly... that is outside of the ring of course.

He did well and for anyone to say otherwise... Well, if your measuring stick for success is multiple title defences, beating all other rivals or an ATG resume then almost every boxer ever is a failure.

Lucas Browne!

 

Tyson Fury actually didn't start boxing till he was 23, he just thought it was just a game of tag till he reached that age

 

Dont know about that - if you follow his social media he’s clearly thick as a plank.

Hopkins

 

That's unfair, he is a boxer, not a scientist. His SM looks just like any other boxer's tbh
