Injury-hit Pakistan suffered another blow when key medium pacer Umar Gul was ruled out for the series-deciding third Test against India because of back trouble, selectors said on Friday.

Gul took a career best 5-31 to help Pakistan win the second Test in Lahore and draw level with India at 1-1 in the three-match series.

The final encounter is due to start on Tuesday at the Rawalpindi stadium near Islamabad.

"We have to name a 17-man squad after injuries to some key players with Gul also ruled out due to a back problem," chief selector Wasim Bari told AFP.

Fast bowler Shabbir Ahmed is nursing a shin injury, while experienced wicketkeeper Moin Khan and allrounder Abdul Razzaq were earlier ruled out of the final Test after failing to regain fitness.

Moin and Razzaq played in the first Test at Multan but pulled out of the second Test with the former suffering a groin injury and the latter hit by backache.

"The injuries are worrying, but I am confident the boys will put this behind them and display the same standard of cricket that earned them victory," Bari said.

India won the first Test at Multan by an innings and 52 runs while Pakistan leveled the series with a nine-wicket win in the second in Lahore.

Pacers Rao Iftikhar Anjum, Fazl-e-Akbar, Abdul Rauf, and allrounder Rana Naved-ul-Hasan have been recalled as backups.

Only Akbar has played for Pakistan before with his last of two Tests against New Zealand in 2001.

Squad: Inzamam-ul Haq (captain), Taufeeq Umar, Imran Nazir, Imran Farhat, Yasir Hameed, Yousuf Youhana, Asim Kamal, Misbah-ul-Haq, Kamran Akmal (wicketkeeper), Shoaib Akhtar, Mohammad Sami, Danish Kaneria, Shoaib Malik, Rao Iftikhar Anjum, Fazle Akbar, Abdul Rauf, Rana Naveed-ul-Hasan.
