Replying to Pakistan Cricket Board (PCB) chairman Shaharyar Khan's letter asking it to be careful with Shoaib as he was carrying an injury, Durham said it had played Shoaib in one match earlier as there was no conclusive evidence about his injury.
"Since the PCB in its final report on Shoaib's injury admitted there was nothing conclusive to be said about his injury, we persuaded him to play the match, although Shoaib was reluctant to play," local daily 'The News quoted Durham as telling PCB.
"However, it was after the match that we realised fresh tests should be conducted on Shoaib and that was where we found he had a stress fracture of the rib," the letter said and promised to give him adequate rest and use him sparingly.
Shoaib said as per the wish of the PCB chief, he had forwarded the report of his second scan to it.
"According to the doctors, who conducted the tests, the fresh report with all other related tests have been sent to PCB through Durham County," the newspaper quoted him as saying.
The second test confirmed injury to his 11th rib as was found in the first test conducted by the PCB.
