Tim Tszyu square off with Terence Spence Jr this weekend to claim the big welterweight title.
Tszyu lost to Spence years ago when he was still a early‑career pugilist.
At present Tszyu aims for the win to erase that memory.
Spence beat him close in court then, now also seeks a decisive win.
The rematch lands live on televised event, giving fans a November rematch option if required.
