What is a supersub?

Under experimental One-day international rules introduced in July 2005, the twelfth man may be substituted for any player; with the substitute able to take over the substituted player’s batting and bowling duties. A twelfth man used as a substitute in this way is known as the supersub. The first supersub was Vikram Solanki, named as a super sub for Simon Jones at Headingley on 7 July 2005. However, as Solanki replaced Jones after England had bowled and England only lost one wicket in chasing down Australia’s target, Solanki did not get to play any part in the game. The ICC cancelled the experiment in February 2006.
