NIGEL Gibbs has cut-short his time at Millwall following the sacking of manager Ian Holloway on Tuesday morning.
Gibbs, who joined the Lions initially as a first team coach in December, moved up to become Holloway's no.2 a month ago.
The 49-year-old was expected to move on at the end of the season anyway but has now stepped aside in the wake of Holloway's departure.
"Gibbo has moved on with Ollie, who brought him to help in the short-term," said chief executive Andy Ambler.
"Gibbo is probably the most honourable man I've met in football after Kenny Jackett, so we've accepted his decision."
Neil Harris, who will be in charge for the final ten games of Millwall's season, is expected to be assisted by former teammate David Livermore.
Livermore has been a youth coach at The Den since 2012, working predominantly with the U18 squad.
