Sergey Shubenkov is among the leading Russian athletes who stand to miss out if the country is barred from international competition. Russia's track and field federation was provisionally suspended Friday by the sport's governing body, keeping the country out of international competition for an indefinite period — possibly including next year's Olympics in Brazil.
