The majority on this list, along with YouTube links, happen to be exhibition matches rather than professional bouts, but still interesting never the less. Enjoy!
Billy Conn vs. Joe Louis III (1948, Exhibition Bout 6 rounds)
Note: Conn/Louis also had an exhibition in 1942, so technically this would have been Conn/Louis IV

And so and so forth, what others can you all list?
*Note: Their first bout was in 1882, and their last in 1897 a period of 15 years. Sullivan would defend (successfully) his title against Ryan also, before Sullivan's unsuccessful tour of Australia as an actor.
