Will this be the final chapter in the fabled career of Filipino legend Manny Pacquiao?
The 40-year-old is aiming to claim a world title for the 13th time in Las Vegas on Saturday night. In his way stands unbeaten reigning champion Keith Thurman, who is 10 years the fighting senator's junior.
Pacquaio (61-7-2) is the bookmakers' favourite to make it 62 wins after a late swing in the betting towards the veteran. Thurman is hungry for a big statement win after a stop-start period in his fine career.
