Yorkshire are furious with Pakistan fast bowler Rana Naved-ul-Hasan after he signed up for the Indian Cricket League (ICL) despite fears that he could aggravate his shoulder injury.
Rana's is due to arrive at Yorkshire in June, but was only expected to start playing top-level cricket in June as his shoulder is still giving him trouble.
Yorkshire Chief Executive Stewart Regan has warned the 30-year-old that the county could review his contract.
"We have written a strong letter to the player and his agent expressing our concern,"
Regan told the Yorkshire Post.
"We have advised Rana that we are not happy and we reserve the right to review his contract when he comes here.
"If there are any suggestions that his injury has been aggravated by playing in that tournament, it could impact on the contract he has to play for us in 2008 and 2009.
"His contract with Yorkshire does not start until April so we cannot prevent him from playing in the ICL. What disappoints us is that he has gone against the advice that the club has given him.
"If we wanted, we could have exercised our get-out clause in December. We could have said 'thanks, but we're not prepared to take the risk'. We have backed him, because he is a player who excites us. He wants to come to Yorkshire - he turned down the chance to go to Leicestershire for more money. We are investing in him for the long-term."
