LONDON, Aug 1 - Poland's Robert Kubica will replace Canadian Jacques Villeneuve in Sunday's Hungarian Grand Prix, the BMW Sauber team said on Tuesday.

Kubica, the team's highly rated test driver, will be the first Pole to start a Formula One race.

BMW Sauber said 1997 world champion Villeneuve had informed them he was not ready to race after his accident at Hockenheim last weekend.
