Banning Russian athletes from international competition is "just something we have to do" if the sport of track and field is to continue to be attractive to athletes, spectators and sponsors, said International Association of Athletics Federations Council member Abby Hoffman on Saturday during an interview with CBC's Scott Russell.

On Friday the council voted 22-1 to place a provisional ban on Russian athletes in the sport of track and field, potentially barring them from competing in the 2016 Olympic Games in Rio de Janeiro, an unprecedented decision.

"Clearly the Russian federation for track and field has been operating outside the parameters of our rules with respect to ethics in general and anti-doping in particular," said Hoffman, a four-time Olympian for Canada who was elected to the council in 1995.
