Samoan sprinter expects to face cheating athletes in Rio

RNZ reports the US born sprinter will run the 200m in Rio later this month, where he's hoping to break the 20 second barrier for the first time.

Last week the International Olympic Committee opted against a blanket ban on Russian athletes for the Games after evidence of state-sponsored doping of Russian athletes in the 2014 Sochi Olympics.

A three-member IOC panel will have the final say on which Russian athletes can compete at the Rio Games, reviewing all decisions taken by the international federations.
