Forest are through to the next round of the Carling Cup after an absolutely magnificent local derby which had to be settled on penalties.
The first half had everything that a cup tie should have, with plenty of fast, attacking football and chances from both sides and there could easily have been more than one goal for both sides.
After a great start to the second half by County, it was Forest who took the lead, but some excellent play by the away side saw them get back on level terms with 14 minutes to go.
With neither side able to break the deadlock the game went into extra time and a superb strike gave County the lead again. But it wasn't all over and Wes Morgan
scored the best goal of his life in the final second to take the game into penalties.
Forest, playing towards the Trent End, came close to opening the scoring after good forward movement by Lewis McGugan
down the right. He played the ball to Robbie Findley
who got away with his pace and fed the ball to Paul Anderson
whose touch was only just wide of the far post.
A good period of pressure by Notts County gave them several chances of taking the lead. First Neal Bishop's long-range shot was comfortably saved by Paul Smith
It was a more difficult save for the Forest keeper when Lee Hughes' header forced him to dive to his left to get the ball away.
And they came close again as they continued to put the Forest goal under pressure with Bishop volleying the ball in. It bounced up for Smith to punch away but only as far as Richard Ravenhill who was unable to find the target.
The goal came in the 21st minute from Alan Sheehan's free kick. The cross came towards the back post and the ball was nodded down into a crowded six-yard box where Mike Edwards managed to stab it in from two yards out.
Forest had a chance to get a quick goal back from a free kick taken by Andy Reid far out on the right. His effort fell for Greening who was well blocked by two County defenders.
Great work by McGugan earned him a free kick when he got past two players before the third stuck out his leg to stop the Forest player in his tracks.
McGugan and Reid both stood over the ball but it was McGugan who took the free kick and crashed the ball into the top corner from 30 yards to level things up.
And they came close to taking the lead when Radi Majewski's cross picked out Reid who headed towards goal from eight yards and Stuart Nelson did well to reach up and tip the ball over the bar.
Findley thought he had got his first goal for Forest after a great cross into the box from Chris Cohen
found the Forest striker who was less than a yard offside when he sent a powerful header into the back of the net.
Both sets of supporters rose to their feet to applaud the players as the half-time whistle went.
County had a chance in the opening minutes of the second half when Mike Edwards' cross was palmed away by Smith before being cleared by Cohen.
And Edwards had another chance from the corner when the ball was played into a crowded box and ricocheted around before being cleared once again by Cohen.
And their good start continued when Ravehill ran onto a cross and shot from a tight angle and Smith did well to get the ball away and out for another County corner.Joe Garner
became the first Forest substitute of the game, replacing Anderson.
Forest took the lead ten minutes into the half after a good ball from Brendan Moloney found Reid on the left hand side. His pin-point cross to the far post found Findley as he ran in and volleyed the ball in from the back post.
And he came close to getting his second when a mistake by County gifted him the ball. He ran clear on goal and sent the ball flying towards goal butNelson managed to tip it over the crossbar.
There were less chances as the half progressed but the pace of the game barely flagged, with both sides pressing forward.
Goalscorer McGugan was replaced by George Boateng with 16 minutes to go.
Former Forest player Craig Westcarr got his side back on level terms just four minutes after coming on as a substitute, shooting on the turn from just inside a crowded penalty area.
And they could have taken the lead after Chambers headed the ball away from the Forest goal, but only as far as an unmarked Karl Hawley and it took a good diving save to his right by Smith to keep the ball out.
County continued to look dangerous and another good save by Smith prevented them from scoring from a magnificent cross in by Montano to Hughes who stuck out his leg and sent the ball towards goal, forcing the Forest keeper to dive away to his left to tap over the crossbar.
As extra time loomed, Forest introduced a third striker when Reid was replaced by Marcus Tudgay.
Forest won a free kick with two minutes to go after Garner was fouled just outside the D. With Reid and McGugan both off Majewski stepped up and chipped the ball over the wall, but just over the crossbar.
There were four minutes of stoppage time for one of the teams to prevent the game going into extra time and it was Forest who looked the more likely to score and when they took a free kick in the final seconds, Tudgay put the ball away but was offside.
Forest put pressure on the County goal in the early minutes of the first period and, from the corner, Morgan and Greening both tried to get the ball in.
But it was County who took the lead nine minutes in when Hawley put the ball through to Lee Hughes who got away and sent the ball flying towards goal where it came off the edge of the far post and in.
Forest came close to getting one straight back when Garner shot on the turn. Stirling got in the way and the ball looped up in the air, forcing Nelson to reach up and tip the ball over. And from the corner Morgan rose at the far post and was only just wide of the target.
Greening had a half chance early in the second 15 minutes, but it was a crowded goalmouth and he sent the ball flying high over the post.
Forest had a chance from a free kick and good delivery from Cohen found Garner who got above his man, but couldn't guide the ball on target and it went over.
A long-range shot from Garner in the final minute almost took the game to penalties, but the ball was just inches wide of the post.
And just as everyone thought it was all over Wes Morgan
scored the goal of his career, sending the ball into the top corner of the net with the last kick of the game.
And with hundreds of Forest fans having already left the City Ground
the game went to penalties.
