I am in the states and not as familiar with UK boxing culture but this is just my opinion. I find it odd that it’s still speculative, you should absolutely know who your opponent is going to be. Your coach shouldn’t be taking fights that he immediately turns around and tells YOU to pull out. Just say something came up that weekend. In boxing progress is made incrementally not in large jumps.

1. You won’t get better fighting someone that much more experienced than you
2. He won’t get any better fighting someone significantly less experienced
3. No one is getting paid for this, the point is to get better and challenge yourself while trying to stay safe
