The PCB has announced a policy for its cricketers under which players wishing to play in the MCL have to obtain a NOC.
Under the questionable policy, players have to sign a letter to announce retirement from international cricket, which would be irrevocable in the future in order to play in the MCL.
"I am already out of the Pakistan team and haven't played top class cricket for a while now so what is the purpose of me announcing any retirement," the 40-year-old Yousuf said.
"I haven't even played domestic cricket for a while now and it is five years now since I played for Pakistan," Yousuf said.

Allrounder Abdul Razzaq, Yasir Hameed Hasan Reza all Pakistan players and have also reportedly submitted their retirements to the PCB.
In Razzaq's case, he is also signed on as a supplementary player with the Lahore Qalander franchise in the Pakistan Super League which will clash with the MCL in the UAE from February 4 to 14.
