Derby 2-2 Southampton
Ricardo Fuller rescued a point for 10-man Southampton after Harry Redknapp and his team looked to have fallen apart at Pride Park.
The striker Redknapp signed from Portsmouth in the summer thwarted a tremendous fightback by Derby, which saw Tomasz Hajto sent off and Redknapp banished from the touchline.
Brett Ormerod had earlier given Saints the lead with his first league goal of the season, but a twice-taken Inigo Idiakez penalty and Andrew Davies' first professional goal looked to have turned the game on its head.
Rams boss Phil Brown gave debuts to Stern John and Peter Whittingham, both of whom signed on loan this week, while Khalilou Fadiga - also on loan - was handed a first start after his substitute appearance in Wednesday's 1-1 draw with Coventry.
Club skipper Jeff Kenna dropped to the bench, with Michael Johnson taking over the captain's armband, while Marcus Tudgay missed out completely.
In stark contrast, Redknapp named an unchanged XI from that which drew 2-2 at Ipswich although Kenwyne Jones returned on the bench after shaking off an ankle problem.
Brown claimed he had a plan to nullify the visitors but a rethink was almost on the cards in the opening exchanges when only Camp's brilliant reflexes prevented Southampton taking the lead.
A delightful one-two released Kamil Kosowski and his whipped cross found Oakley who must have thought he had scored when he connected, but the Rams goalkeeper reacted superbly to keep the ball out with his feet.
That shocked the hosts into action and John won a free-kick on the edge of the area, which Idiakez fired goalward with Antti Niemi heading the wrong way, but Darren Powell was on hand to head clear.
As the half wore on, it looked as though it would take something special to score, although there was almost a freak goal when Fadiga forced Niemi into a fingertip save with a dipping free-kick from out wide - although the offside flag would have spared the keeper's blushes regardless.
And the Senegal international tried his luck in a similar position from open play moments later, only for Claus Lundekvam to clear the danger.
Evidently sensing a need for greater leadership, Brown introduced Kenna at half-time, the defender resuming captaincy duties.
But there was clearly something amiss in the Rams rearguard as Dennis Wise curled in a free-kick which eluded everybody and was only kept out by the post.
Again Brown responded, replacing Fadiga and giving a debut to on-loan Tottenham striker Mounir El Hamdaoui.
The move backfired, as Wise again proved his dead-ball proficiency to set up the opener for Southampton.
The veteran midfielder's free-kick found Fuller, who had space to feed a clever backheel to Ormerod, the striker taking his time to steer the ball past Camp.
Derby had their keeper to thank for preventing Saints grabbing a second, Camp saving well at his near post from Fuller's volley, Wise again providing the ammunition from a corner.
Brown played his last card by introducing Paul Peschisolido and this time his substitution paid off, Derby almost immediately winning a penalty.
Danny Higginbotham - on the other side the last time these sides met more than three years ago - was adjudged to have handled.
There was more drama to come, however, as Idiakez saw his spot-kick brilliantly saved by Niemi - only for referee Nigel Miller to order a retake, much to Southampton's fury.
This time there was no mistake as the midfielder hammered the ball straight down the middle.
That was the final straw for Redknapp who vented his fury and was promptly sent to the stand.
Like their manager, Saints suddenly lost it and Derby won a free-kick on the left-edge of the box, and Idiakez picked out Davies who headed home.
There was worse to follow for Redknapp's men as Hajto saw red for a second bookable offence, and there looked only one winner.
But a Niemi clearance saw Camp advance out of his area to head clear and Fuller showed brilliant composure to lob the ball straight back from fully 35 yards and into the empty net.
