90+7' Finally the full-time whistle brings an end to a pulsating match at Pride Park, which has ended 1-1, after Rob Hulse's first half strike was cancelled out by Robert Earnshaw in the second. Thanks for joining us, bring on the replay at the City Ground on Wed, Feb 4!
90+5' A ferocious challenge from Chris Cohen leaves Howard Webb no choice but to brandish another yellow card - the injury time continues to mount!
90+3' A cross from Commons is punched away well by Paul Smith. Meanwhile, diabolical acting from Rob Earnshaw fails to waste time as he looks away in apparent ignorance of the board displaying his number. The bemused Joe Garner is on in his place.
87' Two unbelievable saves in quick succession from Paul Smith denies first Hulse, then Varney with close-range headers! The keeper has kept Forest in the game with those stops.
84' Kris Commons unleashes a fierce drive which Paul Smith can only parry away unconvincingly. This game is very open now and as both defences tire, expect more clear-cut chances.
76' Arron Davies replaces the injury-stricken Paul Anderson, who leaves the field on a stretcher with an oxygen mask. Paul Connolly is booked for unsporting behaviour.
73' A superb chance for Derby to regain the lead through that man Commons. The substitute found himself at the back post with only Paul Smith to beat, but he misses the target. The ball seemed to get stuck under his feet.
72' Derby bring on former Forest midfielder Kris Commons in place of Gary Teale who receives a very polarised reception - as you can imagine!
64' GOAL!!! Earnshaw has grabbed an equaliser for Forest! More fine work from McCleary down the right finds Tyson in the box, whose dummy leaves Earnshaw to finish clinically past Bywater!
58' Substitute Garath McCleary receives the first caution of the evening after a poorly timed challenge down on the touchline, in front of a furious Nigel Clough.
49' It looks like Nigel Clough will match his opposite number in making a change, with Lewin Nyatanga warming up vigorously on the touchline, as Miles Addison is walking gingerly.
47' Immediately Forest create a bright opening, as Tyson streaks clear of Martin Albrechtsen's marking and brings a save out of Stephen Bywater down low to his right.
46' The second half is underway and Forest assistant manager David Kelly has moved decisively, replacing full-back Joel Lynch with Garath McCleary.
45+1' Howard Webb blows his whistle for half-time, and Derby lead Forest 1-0 courtesy of a Rob Hulse strike. It will be intriguing to see how the visitors respond after the break, after a rousing team-talk by David Kelly.
36' GOAL!!!! Derby's pressure finally takes its toll as Barazite and Connolly again combine effectively down the right, before a deft dummy by Paul Green inside the area leaves Rob Hulse to dispatch his shot beyond Paul Smith!
34' A sharp swivel and shot by Nacer Barazite on the edge of the Forest area brings a parried save by Paul Smith - it was dipping, but the keeper saw his name up in lights by the look of that exaggerated dive!
25' Another ball is whipped in from Derby's right by Paul Connolly almost falls for Hulse, but Ian Breckin makes a sturdy tackle to clear.
23' A great run by Nathan Tyson outpaces Addison down the left, but Earnshaw takes one touch too many, and the chance is squandered.
12' A potentially potent counter-attack from Forest peters out disappointingly as Earnshaw misses his cross when getting to the byline, an impeccably-timed challenge from Jordan Stewart also helped to alleviate the danger, with Tyson waiting in the box.
1' We're underway at Pride Park and the tension is palpable with local bragging rights at stake. Expect some uncompromising early challenges - my money is on Miles Addison to receive the first ticking off from the imposing referee Howard Webb.
- Welcome to this FA Cup fourth round encounter between East Midlands rivals Derby County and Nottingham Forest at Pride Park.
The dugouts will dominate the pre-match attention, with the cameras inevitably trained on Derby manager Nigel Clough. Former Rams boss Billy Davies is absent due to family matters tonight, but Forest will be under the secure stewardship of David Kelly.
