Sunderland have parted company with manager Phil Parkinson after a torrid run of results.
The Black Cats have limped out of the FA Cup in recent weeks, and dropped vital points in the promotion chase.
First team coach Andrew Taylor is set to take charge of Tuesday's game against Burton Albion after Parkinson's assistant Steve Parkin also left the club.
A spokesperson from the club said: "Sunderland AFC has today parted company with manager Phil Parkinson.
"The 52-year-old was appointed in October 2019, overseeing a total of 47 matches during his 13 months at the Stadium of Light.
"Assistant manager Steve Parkin also departs, and the club would like to place on record its thanks to both Phil and Steve for their efforts during their time at SAFC.
"Preparations for Tuesday’s Sky Bet League One fixture against Burton Albion will resume on Monday, with first-team coach Andrew Taylor taking charge of the squad.
"The board will now begin the search for a new manager and will make no further comment until this process is completed. "
