Pakistani Cricket Board on Tuesday refused permission to pacer Sohail Tanvir to play for Hampshire for a short stint in the English county championship.
"I asked the Board for clearance but they said it would be better if I remained with the national team and prepared for upcoming commitments of the national team including the Champions Trophy," said Tanvir, who had been offered the contract through Shane Warne.
Tanvir has been one of the Pakistan's fastest improving players taking five wickets in the last Asia Cup game against Sri Lanka and also finishing as the highest wicket taker in the Indian Premier League where he played for Rajasthan Royals captained by Warne.
"The offer came because of Warne who felt a stint with Hampshire would help me further polish my skills," he added.
The PCB has imposed a restriction on allowing its pace bowlers to play in the county championship because of the growing fitness issues with its bowlers in recent times.
It had also stopped Rao Iftikhar, Mohammad Asif and Umar Gul from signing contracts with counties.
