Three football clubs based in Crimea will play the 2014-15 season in Russia's football league in the wake of its annexation of the peninsula from Ukraine in March: http://www.theguardian.com/world/2014/aug/01/crimean-football-clubs-join-russian-league
Crimea has been rightfully reunited with Russia, it can now play in the Russian league. Only a good thing in my opinion.
So what happens to Ukrainian internationals born in Crimea? Are they eligible for Russia now? Of course if they are any.
