Shabbir's action has frequently been under suspicion
Pakistan seamer Shabbir Ahmed is mulling over his future in the game after being banned for 12 months for an illegal bowling action.
"It is disappointing and in such circumstances one is compelled to think about leaving the game altogether.
"I am very disheartened because I have tried hard to remove any defects in my action," the 29-year-old commented.
The Pakistan Cricket Board is currently considering an appeal, and officials are due to meet Shabbir on Thursday.
"The board knows better what to do - they will decide.
"For my part, I don't know what next course of action to adopt," he said.
Shabbir's action was reported for the second time during the opening match of the recent Test series against England.
And biomechanics experts at the University of Western Australia concluded he does on occasions straighten his elbow beyond the 15 degree limit permitted under International Cricket Council regulations.
Shabbir has played 10 Tests and 32 one-day internationals and the PCB has vowed to provide whatever help is required to enable him to iron out the problem with his action.
"If we need to seek expert help from abroad to resolve his action, it will be done. If he needs to be sent somewehre to correct his action, he will be sent," said spokesman Abbas Zaidi.
The ICC believes a suspension from international cricket was the appropriate step in this case.
"It is clear that Mr Ahmed has the capacity to bowl with a legal action but that on occasion he has the tendency to revert to old habits.
"A suspension for 12 months provides him with the opportunity to permanently address the concerns that have been identified," said chief executive Malcolm Speed.
