Sham, boxrec has Povetkin losing a UD over 12 rounds. Could have sworn he was either KO'd or TKO'd in the 8th. But they deduced a point from Klit in round 11, so I guess I'm wrong. Anyway, here's what they said:
225¾ Wladimir Klitschko 241¾ 60 3 0
Olimpiyskiy, Moscow, Russia L UD 12/12
referee: Luis Pabon judges: Ted Gimza 104-119, Glenn Feldman 104-119, Philippe Verbeke 104-119
