Sussex have announced the death of fast bowler Matthew Hobden.
Hobden was 22. He studied in Cardiff before turning his focus to a cricket career, playing frequent first-class and limited-overs matches for Sussex over the past two seasons.
Sussex said in a statement: " Sussex Cricket is deeply shocked and saddened to hear of the passing of Matthew Hobden.
"Matthew was an exciting young cricketer with a big future ahead of him in the game. He was a fantastic individual who had progressed through Sussex's youth and academy ranks, having been born locally in Eastbourne.
"He made his first-class debut for Sussex in 2014 and had represented the county across all three formats over the past two seasons. He will be greatly missed.
"Sussex would like to offer their deepest condolences to Matthew's family and friends at this difficult time.
"Players and staff will be offered as much support as is possible and we would like both Matthew's family, and everyone connected with Sussex Cricket, to be respected with privacy at this time."
Former Sussex and England wicketkeeper-batsman Matt Prior expressed his sadness at the news.
"Thoughts & prayers with all of Matt Hobden's family at this tragic time," Prior wrote on Twitter. "A great guy with a huge future taken far too soon. #riphobsy
"One of those days when u get a call that puts perspective on things. Live life and love everyday as much as you can! So sad! #RIPhobsy"
Hobden was one of six pacemen chosen to take part in the Potential England Performance Programme (PEPP) this winter, with his potential having been noted as a possible future international.
The group of bowlers were due to spend time in Johannesburg alongside the senior England side, helping with preparations for the upcoming one-day international series against South Africa.
Hobden had two first-class five-wicket hauls on his career record.
England one-day captain Eoin Morgan said: "Thoughts and prayers are with Matt Hobden's family and friends at this extremely difficult time."
