PCB sources said the committee, headed by Intikhab Alam, had recommended that Akmal, fast bowlers Sami and Mohammad Talha and a batsman should be offered central contracts.
All these players were ignored when new contracts were offered in May.
The 21 players, who were offered the contracts, signed them after a delay in June while 21 others were given retainers.
"A decision on offering central contracts to additional players will be taken when the Chairman of the Board Zaka Ashraf returns from abroad," one source said.
Ashraf is currently on vacations in the United States .
Sami's exclusion had caused a big debate in Pakistani cricket circles in May as at that time, he was recalled to the national team for the tour of Sri Lanka but ignored for contracts.
Kamran was recalled to the T20 side for the coming series against Australia and the T20 World Cup in Sri Lanka.
The wicket-keeper batsman in the past has been given category A contracts.
The Board pays a monthly retainer of 313,000 rupees to the category A players, 218,000 to the B category players and 125,000 to the C category players.
