Millwall are expected to part company with head coach Joe Edwards on Wednesday.
The Lions sit 21st in the Championship, just one point above the relegation zone, with 13 games remaining this season.
Edwards – who succeeded Gary Rowett at The Den on November 6 – has won just four of his 19 games in charge in all competitions.
Millwall have lost six of their last seven league games and are without a win since New Year’s Day.
The club are in talks with Cambridge United over a return for Lions legend Neil Harris.
Neil Harris started the season as Gillingham boss but moved on to Cambridge in December
Harris, 46, is Millwall’s all-time record goalscorer and managed the club between March 2015 and October 2019.
He was in charge at Gillingham until October 5 2023, before moving on to Cambridge, where he signed an 18-month deal on December 6.
