The International Olympic Committee on Sunday opted against a blanket ban on Russian athletes for the Aug.5-21 Games after evidence of state-sponsored doping of Russian athletes in the 2014 Sochi Olympics.
The IOC passed the baton to the international federations to clear individual athletes.
"This is a bitter blow for the Olympic movement and we are saddened that our sport in implicated," Simon Toulson, the ICF secretary general said in a statement. "We have taken swift action and removed all offending athletes where doping evidence exists."
The ICF added that it will not impose a federation wide ban for Russia, and issued immediate suspensions to the implicated athletes pending further investigation.
