Middlesbrough have parted company with manager Neil Warnock after Saturday's draw with West Bromwich Albion.
BBC Sport understands former Sheffield United manager Chris Wilder is in line to take over at the Riverside Stadium.
Warnock, 72, celebrated a record 1,602 games as a manager earlier this week, but leaves the Championship club by mutual consent.
Boro dropped to 15th in the table after a 1-1 draw at The Hawthorns and have won just six games this season.
Warnock's assistants Kevin Blackwell and Ronnie Jepson have also left the club after talks following the match.
"The club would like to place on record its thanks to Neil and his staff for all their hard work during their time with us," a Middlesbrough statement read.
