Re: Sohail Tanvir out of the World Cup
I think WC rules allow a team to replace a player who sustains an injury during the tournament.
Kallis for instance is already carrying an injury (rib) and SA have decided to rest him for the first few games. SA won’t (or should n’t) be able to replace Kallis if he aggravates his rib injury while playing WC games
