Jonathan Trott has been ruled out of England's fifth one-day international with South Africa with an hand injury.

Trott was struck by a Dale Steyn delivery during England's six-wicket win on Sunday, but he managed to continue in the middle and score 47.

However, despite an X-ray confirming no fracture, Trott will be forced to miss the final match of the series.

Jos Buttler has been added to the squad for Wednesday's match as England look to seal a series win after their victory on Sunday handed them a 2-1 advantage.
