Kevin Pietersen row disappointing - Graeme Smith

South Africa's cricket captain Graeme Smith says it is "disappointing" that the Kevin Pietersen text message row has overshadowed the build up to Thursday's final Test between England and South Africa at Lord's.

Pietersen was dropped for the third Test against South Africa after sending texts allegedly criticising England team-mates to South Africa players.

Smith says that as far as he was aware the text message were "friendly chatter" but insists it's an issue for the hosts to deal with, saying South Africa must "keep their dignity" and "not get involved".
