IOC: CAS decision to overturn Russian doping bans 'may have serious impact on fight against doping'

The IOC reiterated that the successful appeals do not mean the 28 Russians will be able to compete at this month's Games.

The International Olympic Committee has said it "regrets very much" that 28 Russian athletes have had their doping bans from the 2014 Winter Games overturned on appeal.

It has also warned that the Court of Arbitration for Sport's (CAS) decision could have a "serious impact" on the fight against doping.
