Strange Goings On In SA

Loots Bosman has reacted angrily after being ruled out of the South African Twenty20 squad on medical advice. Bosman claims he feels fine and wants to play. He as also accused coach Mickey Arthur of lying. You can read the cricinfo report here. The strange thing about this story for me is that he has been replaced by Andre Nel. A top order basher replaced by a specialist fast bowler. Is it possible that South Africa suddenly realised thay had the balance of the side wrong and have sought a medical report to get them out of it?
