Russian track and field athletes may be banned from a second straight Summer Olympics after the Athletics Integrity Unit recommended severe sanctions be imposed on the Russian Athletics Federation on Wednesday.
The AIU ordered the national federation to admit its complicity in doping offenses and to show contrition while referring the anti-doping matter to the World Athletics Council with a recommendation that a suspension of the "authorized neutral athlete" process remains in place.
It also said consideration should be given to expelling the Russian federation from the world body.
