Pakistan coach Bob Woolmer confirmed on Thursday that pace bowler Rana Naved-ul-Hasan will not feature in next week's first Test against England at Lord's.
Naved sustained a groin injury while playing for Sussex earlier in the English season and there were fears surgery might be required.
But the 28-year-old has made encouraging progress in his recovery and Pakistan had planned to give him a fitness Test on Friday morning before the start of the tourists' four-day warm-up match against England A at Canterbury.
However, that try-out has been delayed until the weekend at the earliest.
And with Naved not expected to be hitting top pace in the nets until Monday or Tuesday, just days before the start of the first Test on July 13, Woolmer said there was no point jeopardising Naved's fitness for the four-Test series just so he could feature at Lord's.
"He is improving on a daily basis and we were going to give him a fitness test tomorrow. But we have put him back a little bit because we feel he is getting better," Woolmer said on Thursday.
"He won't be available for the first Test match but certainly he could be available after that," the former England batsman added.
"We were going to see how fit he really was and put him through it. But we have just knocked that back two or three days because the groin is getting better and we don't want to rush it too much.
