Jon Lewis, the former England seamer, has been appointed Sussex's assistant head coach. Lewis, who joined Sussex as a player in 2014, took on the job of bowling coach last season and has been promoted as part of the new structure at Hove.
The departure of cricket manager Mark Robinson to take charge of England women last year resulted in Mark Davis' appointment as head coach. Keith Greenfield subsequently became Sussex's first director of cricket, while Murray Goodwin has returned as batting coach.
"I welcome the opportunity of the role as assistant head coach at Sussex," Lewis said. "This will enable me to utilise all my experience of a 20-year playing career worldwide, as well as the coaching experience gained alongside this.
"I will be using my key strengths on a daily basis to help shape a winning side for Sussex, whilst continuing to develop the current bowling group, and future Sussex bowlers. I look forward to working closely with head coach Mark Davis and captain Luke Wright."
Sussex suffered Championship relegation in 2015 and are hoping for a change in fortunes under the combination of Davis and Wright. They will aided by the considerable county knowledge accumulated by Lewis during a career that saw him take more than 1200 wickets across the three formats, as well as represent England 16 times.
Davis said: "It is brilliant to have Jon as my assistant coach. He has made massive strides as a coach over the last 18 months and is an integral part of how we operate Sussex cricket.
"Jon has been an immense support to me in my new role and has been not only been outstanding with the bowlers, but has helped lead the group brilliantly. He has a strong work ethic and an astute cricket brain, and is now part of a very strong coaching team at Sussex."
