Agreed, it's a very intriguing scenario. I was thinking about that as well. And what if Bivol went on to beat Beterbiev / Joe Smith first then moved down at 168 to fight Canelo. We could have 2 Different weight classes Undisputeds being on the line in a single fight. That would be INSANE lol. Apparently the last time two Undisputeds fought each other was in 1974 when Undisputed Middleweight Champ Carlos Monzon fought Undisputed Welterweight Champ Jose Napoles in 1974, but that was fought at Middleweight. This could be an actual Undisputed vs Undisputed if Bivol unifies LHW first then moves down.
