An afternoon that started full of promise ended in defeat for Forest against local rivals Derby as Forest still wait for their first home League win of the season.
With Derby down to ten men and Forest a goal up within the first five minutes, Forest looked set for a win. But Derby were back on level terms just before the half hour mark and grew in confidence as the half progressed.
Forest started the second half well, but it went downhill from there and when Derby took the lead they threw everyone back into defence and Forest were unable to find a way through.
It could not have been a more dramatic start to the game when, in the second minute, Matt Derbyshire broke into the box and spotted Ishmael Miller running in. He knocked the ball past the keeper from six yards out and Frank Fielding stood in his way, bringing the Forest striker down.
The Derby keeper was immediately shown the red card by the referee and Tomas Cywka had to be substituted before he had even touched the ball.
Stepping up to take the penalty, Andy Reid looked calm as he walked slowly back from the ball and kept his nerve as he ran back to shoot, sending the ball to the right as substitute keeper Adam Legzdins dived to his left.
The pressure all came from Forest as they pushed forward again and again with Derby only managing the occasional break, giving Lee Camp nothing to do.
Forest looked much better on the ball, unafraid to get stuck in, they won nearly every tackle they went into, although they were again let down by the final ball.
Derby controversially got back on level terms in the 29th minute when the referee allowed play to carry on, with Chris Cohen lying injured in the Derby half.
Derby pressed patiently forward into the box and Forest allowed Jamie Ward to get away from Radi Majewski and Chris Gunter to beat Camp at the near post.
The stretcher came on but eventually Cohen managed to limp slowly off to be replaced by Joel Lynch.
Derby came to life after the goal and started to look more threatening going forward, but Forest still made the extra man count when Miller made a superb break and fed the ball across to Wes Morgan as he ran forward, but the Forest defender looked unsure what to do with the ball and wasted the chance.
Forest came close just before half time when Lynch chipped the ball in and Legzdins got a hand to it. He was unable to keep hold of the ball under the challenge of Miller, who was judged by the referee to have fouled the keeper, just as the ball looked like it might creep over the line.
And there were cries of hand ball when a great free kick into the box by Reid appeared to hit an arm in a crowded penalty area, but the referee waved play on.
Forest pressed forward at the start of the second half and some patient build-up play ended when Majewski fed the ball to Reid, whose effort went over the crossbar.
And a shot along the ground from Miller from just inside the penalty area was easily saved by Legzdins.
Reid came close from a free kick 25 yards out and the Derby keeper had to parry the ball round for a corner, which was also cleared by the Derby defence.
On the hour mark, Robbie Findley came on to replace Jonathan Greening and provide an injection of pace up front for Forest.
Great delivery into the box by Lynch threatened but was bravely headed away by Mark O'Brien.
For a split second it looked like Derby had taken the lead with a shot from Jeff Hendrick, who picked up a ball at the far post, but he headed just inches wide of the far post from four yards.
Forest then came closed when Findley fired over a cross and Derbyshire dived in to try and turn the ball towards goal, but it flashed wide.
There were loud cheers for Lewis McGugan, in contrast to the boos that Nathan Tyson had received from the Forest crows a couple of minutes earlier, with Reid the player to make way for him.
McGugan was involved straight away with a well-taken corner into the box, but the header at the back post flashed wide.
Derby took the lead in the 73rd minute when Forest were unable to get the ball clear following a corner.The ball went back towards the goal where Hendrick crashed it low into the left corner of the net from the D.
Forest were quickly on the attack and Chris Gunter's cross found Derbyshire, but he headed the ball straight into the arms of the keeper.
And with Derby pushing all ten men back into defence, Forest struggled to get through on goal.
They came close when Lynch chested the ball past a defender and from the corner of the six-yard line he smashed the ball in, forcing the keeper to put the ball out for a corner.
And they threatened again from McGugan's free kick on the by-line but again, with ten men defending the goal, Forest could not find a way through.
In stoppage time a low ball into the box by Lynch found Derbyshire, but substitute Russell Anderson managed to stick out a foot to deflect the ball.
A volley by Chambers from ten yards out flew over the crossbar and even with Camp coming up to help with their final chance of the game, it was not to be.
