Pace bowler Tom Taylor has been ruled out for the remainder of the 2016 season with a stress fracture of the lower back.
The 21-year-old suffered the injury earlier this month and a scan revealed a stress fracture which will keep him out of action for the rest of the year.
Taylor, who was on the Potential England Performance Programme in the winter, made three first-class appearances for Derbyshire this summer, the last coming against Sussex at Hove at the end of May.
