Dan Martin has left his role as manager of Heanor Town.
Martin, who was appointed in the summer to replace Paul Postlethwaite, has overseen a mixed start to the East Midlands Counties League season with two wins, two defeats and a draw.
His last game in charge was a 3-0 win over Barrow Town on Saturday, which left the Lions 12th in the league standings.
Martin said after the game: "I've resigned as manager as I don't have the time to devote to the role and the club deserves someone in charge who does. Things have got on top of me a bit and I need to take a backward step and concentrate on things in my personal life.
"I've been proud to manage the club even for a short period of time and it will always have a place in my heart, but hopefully the new manager comes in and see that the lads care and that the quality is there. When people put us under pressure and say it isn't, hopefully the performance against Barrow proves them wrong."
The Lions are next in action on Saturday with a home game against Selston.
