Head of performance Ross Burbeary has left the Imps to take up a senior role at Derby County.
Ross will be reunited with Paul Warne, whom he worked with for many years at Rotherham United prior to joining City, having completed a restructure of the club’s medical and performance team.
Imps chief executive Liam Scully said: "Together with Ross we have designed and implemented new methodologies and practices across the club which will last well beyond his time with us.
"We thank Ross for his contribution to Lincoln City and he leaves with our thanks and best wishes."
