Rio 2016: Russian swimmers Morozov and Lobintsev appeal against Olympics ban
Russian swimmers Vladimir Morozov and Nikita Lobintsev have become the first athletes from the country to appeal against their Olympics ban.
The pair have filed requests with the Court of Arbitration for Sport to have their bans declared "invalid and unenforceable".
Both swimmers were named in the McLaren Report which revealed state-sponsored doping in Russia.
A panel of arbitrators from CAS will decide the next steps for the appeals.
