Sussex have revealed Reece Topley will leave the club after rejecting a long-term contract offer.

As a free agent and following back surgery, the 25-year-old was helped back to fitness by Sussex’s medical and coaching staff earlier this year before joining the county for the remainder of the 2019 season in July.

Topley praised Sussex's part in helping him back to fitness at the time and the left-arm seamer played his first T20 Blast and Championship matches since the 2017 season.

A statement from Sussex said: "Sussex Cricket is disappointed not to have been able to convince Reece to resign for the club.

"Nevertheless, we would like to thank him for his contributions to the team during the season and to wish him well at his new club."

The former Essex and Hampshire bowler's decision will come as a surprise and disappointment to Sussex, who announced head coach Jason Gillespie had agreed a new long-term deal earlier today.

Topley's arrival at Hove came after an invitation from Gillespie as revealed in The Argus earlier this summer.

Topley announced his return to playing in July told The Argus:  “The initial contact between us came when Dizzy (Gillespie) called me to check on my situation I was in Melbourne training with the Renegades and Victoria cricket.

“I told him I didn’t really want to be involved in a contract as I felt they had been hindering me.

“I was playing, getting injured, coming back and getting injured again.

“It felt like an endless cycle so I wanted to take a step back and sort it out in my own time.

“I wanted to be very cautious about how I came back and it was good faith on Sussex’s part as they said I could pick up from wherever I was when I got back to England with them.

“They said I could bowl at the guys in the nets, work with the coaches and physios and get out of it what I need.

“I’ve liked that because I’ve had a lot of control which I have not had in the past.”
