Boston United have sacked Graham Drury as manager after just 13 games and appointed former Histon boss Dennis Greene until the end of the season.
Greene was overlooked by the Pilgrims for the position when Drury was named in mid-December.
Drury took over with Boston 11th in the Blue Square Bet North table, six points off the the play-offs.
But they only won two games and Drury was booed by some fans on Saturday after a third consecutive defeat.
The loss against Vauxhall Motors means the Pilgrims remain 10 points off the relegation zone, but all the teams beneath them have games in hand.
Chairman David Newton told BBC Radio Lincolnshire: "Results have not panned out as we all wished and unfortunately we have reached the decision to part company with Graham.
"It's a club that Graham always wanted to manage and he was full of enthusiasm and that in the end swayed our decision to hire him."
Newton, who admitted that Drury was not his first choice, also added that new boss Greene impressed him with his track record.
"He's a guy who knows what he is doing and he knows he is putting his neck on the line a little but in the current position but he is prepared to roll his sleeves up and try and earn himself a contract for next season," he said.
The Pilgrims, who are 15th in the table, host Gloucester on Tuesday.
