"It's impossible for me to recover from injury without the help of the Board because I need to go aboard for treatment," said the national paceman yesterday.

A frustrated Sharif came to talk to team physio John Gloster at the Bangabandhu National Stadium during the national team's reporting for a residential camp.

Gloster informed that Sharif, who last played against Pakistan at home in January 2002, needed at least six months to make a full recovery.

It was earlier thought that the promising bowler had a groin problem but Gloster told him it was more to do with his bones than his groin.

"It is due to a friction between groin joints. It happens mostly with footballers and takes a long time to overcome," he said.

"Sharif feels the problem when he is about to deliver the ball. I will discuss his problem with experts in Australia."
