India fast bowler Zaheer Khan will not be replacing New Zealand's Shane Bond at Warwickshire, as talks between him and the club failed.
The English county said Khan could not confirm his availability because of international commitments with the national team.
"We got to the stage of discussing a contract with Zaheer Khan, but similar to Shane he could not commit because of international duty," Warwickshire operations manager Keith Cook told the BBC Sports web site.
"We need a player to be available for five championship and seven one-day matches while Shane is away, and Zaheer felt he would be unavailable for two of the four-day games."
Bond is set to miss the first two months of the domestic campaign because of international commitments with New Zealand.
"We are looking at two other players, which I won't name, but we are closer to making an offer and should be ready to name somebody by Wednesday," Cook said.
