Warwickshire have lost fast bowler Oliver Hannon-Dalby to injury for up to six weeks.
Hannon-Dalby suffered a side strain on the opening day of their County Championship match with Middlesex on Sunday.
He will not be able to bowl again in the match and looks set for a lengthy spell on the sidelines.
The former Yorkshire quick missed much of his first season at Edgbaston because of injury and he had started the season well. He had already taken two wickets in his first four overs against Middlesex when he suffered the injury.
