Player-coach Daryl Clare has been promoted and is now Boston Town’s assistant manager.
The former Grimsby Town and Boston United forward will replace former number two Andy Liddle.
Manager Nathan Collins said: “Andy can’t fully commit due to his work situation.
“I would like to thank Andy for all his hard work and wish him well in the future.
“I am really looking forward to working with Daryl and first team coach Paul Fenwick.”
Clare has managerial experience as the former boss of Louth Town.
Fenwick joined the Poachers last week, following three seasons as Brigg Town’s number two.
