* UKAD awaits CAS explanation * Olympic rival calls decision “shameful” By Mitch Phillips RIO DE JANEIRO, Aug 2 (Reuters) – The head of British anti-doping said on Tuesday she was still waiting to hear from the Court of Arbitration for Sport (CAS) for a full explanation of why it overturned a ban for road cyclist Lizzie Armitstead for missing three doping tests. The 2015 world champion and 2012 Olympic silver medallist was facing an automatic ban under the “whereabouts system” after three missed tests within a year but CAS upheld her appeal that correct procedures were not followed for the first of the tests, allowing her to compete in Rio. Nicole Sapstead, chief executive of UK Anti-Doping (UKAD) issued a statement on Tuesday questioning why Armitstead did not challenge the initial missed test finding last August, choosing to do so only last month after two subsequent missed tests triggered the ban last month, which was kept secret.
