League One side Sunderland will not be reappointing Roy Keane as their new manager, BBC Radio Newcastle reports.
The 50-year-old Irishman had a two-year spell with the Black Cats between 2006 and 2008, during which he led them to the Premier League.
He entered negotiations with the League One club last week but it is now understood he will not be returning.
The Manchester United legend has been out of football management since leaving Ipswich in 2011.
Sunderland were second in the table after their most recent league win over Portsmouth on 22 January, however a thumping 6-0 defeat at Bolton in their next game saw boss Lee Johnson sacked and they have subsequently lost against Doncaster and Cheltenham to drop to fourth.
