MILLWALL have tonight sacked manager Steve Lomas.
The Lions board decided unanimously to terminate the contract of the Northern Irishman in the wake of the 4-0 loss to Watford.
Coach Neil Harris and academy boss Scott Fitzgerald have been placed in temporary charge of first team affairs.
Chief executive Andy Ambler said: "We are very disappointed that it hasn't worked out for Steve.
"He has been thoroughly professional in his approach to the job during his short period with the club and remains a very promising young manager.
"However, the board feels that it is in the best interests of Millwall that we make the change at this time and the search for a successor to Steve begins immediately.
"We thank Steve for his efforts and wish him the very best for the future."
Defeat at Vicarage Road on Boxing Day was Millwall's fifth in their last eight league matches, a result which left them just three points above the relegation zone.
The club's directors had called for a big "reaction" against the Hornets after losing 2-0 to Middlesbrough last Saturday, but Lomas' side produced another disappointing performance.
And that has proven to be the final game of Lomas' tenure at The Den, which began in June when he was appointed from St Johnstone.
In total, Lomas won six, drew six and lost 12 of his 24 games in charge.
