A senior official of the board told PTI that the contracts for 2015 would be announced after the series and that a few clauses needed to be finalized in the new contracts which have already been delayed by five months.
A well-informed source told PTI that the delay was due to the players resistance to the board's decision to remove the clause of win bonuses for the team for all three formats.
"Obviously the players are not happy with the removal of win bonuses for test, ODIs and T20 matches as this was a big incentive for the team to do well," the source said.
"There is a feeling in the board that given the disappointing performances of the players since last year they need to first improve their results than claim to have a right to win bonuses as well," the source added.
