Eleven Pakistani players participated in the inaugural edition of the IPL. However, the franchises retained the contracts of only four of them for the second season following the Mumbai terror attacks.

The IPL release said that during the next season pink balls would be used for practice matches. ne of the major changes in the rules for the next season would be that each team would be allowed four fielding substitutes instead of the mandatory twelfth man.
