I think that's alright, Tim Tszyu doesn't have to rush things just to come back at the winning path, his health is still the most important concern as that 1 loss of his career is not yet a carreer ending one. he'll rest but stay condition, so once he is already given a signal, he can still be at his 100%.
So everything is up to Spence now, he was given this opportunity to fight for a world title and hopefully he won't waste it so that we can still the rematch between him and Crawford at 54 when they are champions, I think that is the plan.
That's a good plan, at least a win here will make him a chamption and if Crawford will become a champion in his division as well, they can also have a rematch, at least one chance for Spence to proved himself, but if he wins, then we will be seeing one of the biggest fight as the hype of these two will be back again, and it will be 50/50, just like the first fight between the two.
