Uwe Rosler has been sacked as head coach of League One side Fleetwood.
The Cod Army suffered a seventh straight defeat as they lost 3-0 at Doncaster on Saturday - a result which left last season's League One play-off semi-finalists languishing in 20th, above the relegation zone on goal difference.
A club statement confirming the decision read: "Everyone at Fleetwood Town would like to place on record their thanks to Uwe for his hard work and professionalism during his time at the club.
"The search for his replacement will begin immediately, with Barry Nicholson and David Lucas taking charge of Tuesday's game against Portsmouth."
Ahead of the visit to Doncaster, former Brentford, Wigan and Leeds boss Rosler spoke of the importance of getting something from his side's trip to the Keepmoat Stadium.
"It's an important game," he told Fleetwood's website the day before the game.
"We want to win every match, but they are near us in the league, so it is very important we leave with something."
Immediately after the defeat, Rosler admitted he was concerned by the manner in which his side had conceded.
Rosler replaced Steven Pressley as Fleetwood boss on a two-year deal in 2016. After leading the club to a fourth-place finish in League One, the former Manchester City striker signed a new contract with the club, which would have taken him through to 2020.
