Before the tour starts, several senior players in the team are reportedly going to meet with the sports minister to seek his permission for their move.
The team that participated in the T-20 World Cup which they had gone onto win, too, had not signed the contracts, citing various shortcomings.
The deadline for the players to sign the contract ended at 4.00 pm today (20), but none had done so.
Meanwhile, the SLC is reportedly planning to send a different team for the Zimbabwe tour if the players do not sign the contracts.
The players rejected the contracts over certain newly-added conditions, but moderate critics approve the terms in the new contract.
However, they are critical of the manner SLC had chosen the 70 players under youth and domestic categories.
The critics allege that that had been done to the want to three top SLC officials.
