Who has boxed the most rounds?

[El.Naranjito707]

I was on boxrec.com and was checking out some old school fighters and some of the newer generation ones and was looking at the rounds boxed...
1.Roberto Duran with 822 Rounds
2. Hector Camacho with 673 Rounds
3. Julio Cesar Chavez with 633 Rounds
4. Muhammed Ali with 549 Rounds.

Anyone know any other guys from the past that have a high number and what modern generation fighters have the most rounds boxed?

I'm not 100% sure on if anyone has more but Len Wickwar boxed 3974 rounds and has the most recorded bouts.
