Holbeach United will step up the search for a new boss this week.
Caretaker-boss Martyn Cundy has decided not to carry on with a long-term role following two games in charge.
Martyn has been very honest and open so I fully respect his decision.Dave Dougill
He took over when Tom Roberts resigned due to work commitments.
Cundy said: “We had a meeting on Sunday when I was totally honest and told the chairman that I can’t be 100 per cent committed to a management role.
“I’ll help out until a new manager comes in but even if I carried on, it would only be until the end of the season.
“The club needs someone to stay for three or four years.
“I’ve got eight-year-old twin daughters who are busy with different activities so I don’t have the time to go out and watch games or contact players.”
Tigers chairman Dave Dougill said: “There will be another meeting this week and we’ll look at interviews for a new manager.
“We’re trying to find somebody who can stay here for a few years.
“Martyn has been very honest and open so I fully respect his decision.
“He has got a young family and he feels being a manager would be too much commitment. It wouldn’t be fair on his wife.”
Holbeach were forced to call up reserve players due to injuries and unavailability on Saturday so the PFA Senior Cup tie at Pinchbeck United was called off.
Two late goals sent the Tigers to a 3-2 defeat at Sileby Rangers in the ChromaSport & Trophies United Counties League Premier Division.
They led 2-1 with just nine minutes left following goals from Aaron Eyett and Tommy Treacher.
Cundy said: “We were under strength but we deserved to get something out of the game. It was very disappointing.”
