After just two seasons with the county, specialists have advised that the Cardiff MCCU player would risk serious damage if he were to continue playing after he aggravated the injury in a second XI match against Somerset.

Murphy score over 500 runs in the 2018 County Championship, including a career-best 80 against Kent.

“I will always be proud of my time and achievements with the club, especially the game against Kent last season,” he said. “Although it is going to be a difficult period transitioning out of the game I love, I am excited about what the future holds, the opportunities that await me and turning my dedication to a new profession.”

Director of cricket Mark Wallace added: “Jack is a very popular member of the dressing room and the club in general and it’s very sad for Jack and his family that he has had to cut such a promising career short due to the injury.”
