Pakistan batsman Mohammad Hafeez has been ruled out of the skills camp beginning on May 28 at the National Cricket Academy in Lahore, but doctors will continue to monitor his recovery from a knee injury on a weekly basis ahead of Pakistan's tour of England which starts June 18.

A fresh MRI scan on Hafeez revealed an improvement in his knee, first injured in March, but stress has been diagnosed and he may be rested for some time as a part of his continuing rehabilitation regimen. He had already missed the ongoing fitness training camp at the Pakistan Military Academy in Abbottabad.

Hafeez last played for Pakistan at the World T20 in March where he sustained the knee injury after a bone contusion in his femur. He has been resting since then and undergoing extensive treatment as a part of his rehabilitation. According to the latest report, doctors advised Hafeez against any net sessions. ESPNcricinfo understands Hafeez is desperate to restart his cricket but doctors are cautious about his injury which they fear could be aggravated if he tries to push for an early return.

A final call on his participation in the England Test series is expected to be taken in the next three to four days. Pakistan's 22 probables will be cut down to a final 16-man squad at the conclusion of the skills camp. The squad will leave for England to undergo a conditioning camp in Hampshire ahead of two practice matches in Somerset and Sussex before the first Test starts July 14 at Lord's. The selectors had named four options among the probables for the opening slots, with the inclusion of Hafeez cited as subject to fitness.
