Pakistan responded to their crushing 354 run first Test defeat by England at Trent Bridge on Sunday by recalling former captain Mohammad Yousuf and so ending the batsman's international exile.
The Pakistan Cricket Board (PCB) also announced leg-spinner Danish Kaneria had been released back to English county side Essex ahead of the second Test at Edgbaston, which starts on Friday.
A brief statement issued by the PCB in Lahore said: "Danish Kaneria is released from the national team and he is now available to play for his county Essex. His services will be available for national squad if required.
"Mohammad Yousuf and Raza Hasan (a left-arm spinner) are added to the national squad with immediate effect."
Kaneria was dropped after a hugely expensive match return of one wicket for 171 runs at Trent Bridge.
Yousuf, a batsman of proven Test-class, announced his retirement from international cricket in March, having been handed an indefinite ban by the PCB following Pakistan's disastrous tour of Australia where the team failed to win a single international match.
His recall came just hours after Pakistan were bowled out for 80 - their lowest ever Test total against England - at Trent Bridge.
