Millwall have sacked manager Ian Holloway with the club eight points from safety in the Championship.
Holloway, who has been at Millwall since January last year, has guided the club to just seven league wins this season - and Millwall are currently without a victory in six league matches including Saturday's 4-1 home defeat to Norwich for a fourth-consecutive defeat.
Sky Sports News HQ understands Holloway was informed of the club’s decision by chief executive Andy Ambler on Monday night.
Millwall’s board members made the decision after noting performances had improved, but not results.
It is understood that Millwall are not actively pursuing a long-term replacement, with Neil Harris in charge until the end of the season.
Millwall chairman John Berylson said: "This was a hard decision to take because we very much hoped that Ollie would prove to be the man to take us forward and on to the next level.
"I would like to thank him for his efforts, and in particular for keeping us in the Championship last May.
"This season, though, has proved to be an extremely challenging one and we now find ourselves facing another uphill battle to avoid relegation.
"Ian Holloway remains a fine manager and it was his impressive track record which led us to appoint him some 14 months ago. However, our view is that the decision to part company at this stage is in the best interests of the football club going forward.
"Neil Harris has agreed to take over managerial duties for the remainder of the season and I am confident that Millwall fans will give him every support over the next couple of months as we strive to turn our current run of form around."
Former Millwall striker Harris is a coach at The Den and has been in charge of the club's U21 development squad.
