Tim Tszyu square off with Terence Spence Jr this weekend for the big welterweight title.
Tszyu lost to Spence years ago when he was still a junior boxer.
Now Tszyu seeks the win to erase that memory.
Spence beat him by a thin margin in court then, now also seeks a decisive win.
The rematch comes live on PPV, giving fans a November rematch option if needed.
