The club confirmed that he has been able to rescind his resignation, and will return to the BetVictor S/East Division side, who sit fourth in the table.
Speaking to the Nailers website, Mick said, "Before breaking up for Christmas I had news that was going to make it difficult for me to commit to my role as assistant manager.
"This would have been unfair on the lads, the gaffer and the club to carry on when I couldn't give 100%. I reluctantly handed in my resignation but since then circumstances have changed again.
"I spoke to Grant to see if it was possible to come back and finish off what we have started and I'm glad to say that he spoke to the club and they agreed."
