Neil Warnock has become the first Premier League manager to be sacked this season after being dismissed by Crystal Palace.
The 66-year-old joined the Eagles for a second time in August 2014, following the departure of Tony Pulis.
He leaves with Palace in the relegation zone after a 3-1 home defeat by Southampton on Boxing Day.
Assistant manager Keith Millen will be in charge for the trip to Queens Park Rangers on Sunday.
It is understood Palace are looking to appoint a permanent successor as soon as possible.
A club statement read: “The club would like to put on record its thanks to Neil for all his hard work and energy over the past four months.”
