Tim Tszyu faces Terence Spence Jr this weekend to claim the significant welterweight title.
Tszyu was beaten by Spence years ago when he was still a early‑career pugilist.
Now Tszyu seeks the win to erase that memory.
Spence beat him narrowly in court then, now also pursues a decisive win.
The rematch lands live on PPV, giving viewers a November rematch option if required.
