The Wasps signed Russian hooker Vladislav Korshunov, who skippered his country at the 2011 World Cup and has won 57 caps, and flanker Victor Gresev, the 2011 Russian Player of the Year and the Man of the Match in the World Cup games against Italy and Australia.
Korshunov will provide cover for Rob Webber who is in the England Elite Player Squad, while Gresev adds strength in depth to the back-row, an area significantly affected by recent injuries.
