Dutch gymnast Yuri van Gelder has been expelled from the Olympic Games by the Dutch Olympic Committee and will be sent home immediately for violating team rules, including consuming alcohol. …
In 2009, van Gelder was suspended from competition for one year by the KNGU after testing positive for cocaine during a competition. He underwent a three-month drug treatment in Scotland. However, in October 2010, he was withdrawn from the world championships in Rotterdam after admitting subsequent cocaine use.
He will be replaced in the Rings final by French gymnast Danny Pinheiro Rodrigues.

It’s great to see a Federation step up and do what’s right, rather than just be focusing on a Finals slot.
