The Scot had previously declared the deal dead.
Although, at one point, it looked like they might actually lose the game. Despite being the better side for much of the game Forest found themselves 1-0 down to a Jonathan Parr strike.
But they equalised in the last minute of injury time after a player who only signed for the club this morning poached in for a tap in. Liam Trotter secured a point after firing home after Jorge Grant's shot had been saved.
Trotter only signed this morning on loan from Bolton Wanderers. The deal did not look like happening, with Forest manager Dougie Freedman even telling his press conference yesterday that the deal was as dead as the dodo.
Now he has described the mad situation behind the signing and how happy he was with Trotter's performance.
BBC Radio Nottingham quote him as saying:
"I thought he was fantastic today and definitely deserved his debut goal.
"We get a letter from the Football League at 18.45 saying we were clear to go. Delighted he signed this morning.
"If I don't like it, I can walk away tomorrow morning, but I love it."
Trotter was not a universally popular arrival at Forest this morning but this goal would have gone a long way to suppress the doubters among the Forest faithful.
He will now be hoping to push on and grab some more goals for the club.
