Salman Butt will take over the Pakistan captaincy for the second and final Test with Australia after Shahid Afridi stepped down from the role.
Butt had already been confirmed as Afridi's successor after the big-hitting batsman announced his resignation after defeat in the first Test at Lord's on Friday.
As well as giving up the captaincy, Afridi revealed that he would retire from Test cricket after admitting to no longer having the temperament for the longest form of the game.
The second Test at Headingley was thought to be his last, but it has now been revealed that he has been released from the squad and will not feature in that contest.
"Salman Butt will be the captain for the next five (Test) matches, starting against Australia in Leeds," Pakistan tour manager Yawar Saeed told AFP.
Butt takes the reins as Pakistan try to level the series after a 150-run loss at Lord's before embarking on a four-Test series with England.
Wicketkeeper Kamran Akmal has been handed the role of vice-captain, a position formerly held by Butt.
After the first Test Afridi said that 25-year-old Butt - who top-scored in both innings with 63 and 92 - was ready to take over as captain.
He said: "Salman is showing his maturity. He's good enough to take over this team as captain."
