Tim Tszyu faces Terence Spence Jr this weekend to claim the big welterweight title.
Tszyu was beaten by Spence years ago when he was still a junior boxer.
At present Tszyu desires the win to erase that memory.
Spence beat him close in court then, now also hunts a clear victory.
The rematch lands live on pay‑per‑view, giving fans a November rematch option if necessary.
