Derbyshire have confirmed wicketkeeper Tom Poynton will miss the rest of the season.
Poynton suffered leg injuries in an April 4 car crash that claimed the life of his father Keith.
Further investigations by specialists have revealed the problem to be more serious than initially anticipated, and Poynton will therefore play no further part this summer.
Coach Graeme Welch said: "We are all bitterly disappointed for Tom.
"He'll get the best possible support from our medical team during his rehab and will remain very much a part of the group.
"It's a setback for the lad, but he's a resilient character and a strong professional.
"He'll throw himself into rehab and come back fitter, stronger and more determined than before."
With Richard Johnson also out with a 'sports performance anxiety issue', Derbyshire have signed former Lancashire keeper Gareth Cross on a deal to the end of the season.
Cross had been playing for Derbyshire's Second XI since being released by the Red Rose county at the end of last season and he will go straight into their squad after loanee Dan Hodgson was returned to Yorkshire.
Welch added: "Gareth is an experienced wicketkeeper-batsman and we are delighted to have him at the club.
"It's testament to the relationships and contacts within our elite coaching structure that we managed to secure such a top signing when we needed it.
"He's a very good batsman who can score quickly. He's also very tidy with the gloves and his attitude during the trial period with our second team has been top draw."
