“A further update will be provided to supporters as soon as is practical.”
Nancy was under growing pressure after their Old Firm rivals came from behind to win at Parkhead on Saturday.
He had insisted after the game he was “very close” to turning things around – and still believed Celtic were title contenders.
“It’s the results. Results. So this is the reality for the moment, he said.
“But when I say this is the reality, it doesn’t mean that I am a defeatist guy. No.
“What I mean is we are really close, really, really close, to turn things around.”
He added: “And again, I know that we lost but I have also to be objective.
“The level that we had at certain moments was really, really, really high. This is the reality.”
