Championship side Middlesbrough parted company with manager Garry Monk hours after a 2-1 win at Sheffield Wednesday.
The former Swansea and Leeds United boss has been replaced by academy manager Craig Liddle on an interim basis "while a successor is appointed", the club said.
Middlesbrough are ninth in the league and have won 10 of their 23 games.
News of Monk's departure was announced on the club's Twitter feed and comes just six months after he was appointed.
Monk took charge of the club in June and was tasked with leading the side to promotion back to the Premier League.
He oversaw just four wins in Middlesbrough's first 13 league games but the club won six of their next 10 games to move to within three points of the play-off places.
Good. Always thought he was overrated.
