Sunderland have sacked manager Jack Ross in the wake of Saturday's 2-0 defeat to Lincoln City.
Ross joined Sunderland in 2018 as permanent successor to Chris Coleman but was unable to guide to club to immediate promotion back to the Championship, losing to Charlton in the League One play-off final.
The Black Cats have struggled for consistency at the start of the new season and a 2-0 defeat to Lincoln City has left the club sixth in League One, eight points behind leaders Ipswich Town.
