Match ends, Southampton 2(3), Derby County 2(5).
Derby recovered from a two-goal deficit to edge past Southampton 5-3 on penalties in a thrilling FA Cup third-round replay at St Mary's.
Two goals in two minutes from Stuart Armstrong and Nathan Redmond had put the hosts on course for victory, after the visitors had earlier had a Craig Bryson goal disallowed by VAR.
But Harry Wilson's free-kick sparked a revival before Martyn Waghorn headed a late equaliser for Frank Lampard's side.
Redmond missed in the shootout for Southampton, allowing Rams captain Richard Keogh to strike the winning penalty.
Derby travel to League One Accrington in the fourth round on Saturday, 26 January (12:30 GMT).
Inseparable after 210 minutes
For the second successive meeting Derby displayed resilience to recover after falling two goals behind to Southampton, leaving the sides inseparable after 210 minutes of football.
In a game full of incident, it seemed the visitors had drawn first blood when Bryson produced a composed left-footed finish past Saint goalkeeper Angus Gunn in the first period.
But after a wait of two minutes, VAR judged forward Waghorn to be marginally offside before he played in the midfielder.
The introduction of Redmond helped Saints up the tempo after the break and they looked to have put the tie to bed with two goals in two minutes.
First Armstrong nodded in from close range to conclude a fine move involving Mohamed Elyounoussi and Shane Long. Jack Stephens then released Redmond who delivered a deft chip over Rams goalkeeper Kelle Roos.
Derby arrived on the south coast having lost eight of their past nine FA Cup games at Premier League opponents, but that statistic was clearly not on the players' minds as they surged forward to force a free-kick that Wilson curled home beyond Gunn - but only after more anxious moments following a VAR review.
And the battling visitors pulled level when Waghorn found the top corner with a well-placed header, forcing a goalless period of extra time before the successful shootout against last season's semi-finalists.
Derby's players showed great composure to convert all five of their penalties, with Southampton's only failure from 12 yards coming from the otherwise impressive Redmond, who sent an ugly effort wide of the mark.
'It's the FA Cup, it's magical' - what they said
Southampton manager Ralph Hasenhuttl speaking to BBC Sport: "Congratulations to Derby County. When they fight like they did in the two games, they deserve to go through to the next round.
"We didn't deserve to win. We had a few chances and didn't get the goal. We given the lead away two times so it was very disappointing. It was very frustrating. We were not very good in the first half so made changes to the system at half-time. Second half we were much better and played well for the two goals.
"But they got a goal from a set-piece and you could feel everybody thinking about the first game and getting a bit nervous. The opponent was in the right place to score a second time, and both sides had less power in extra time. We still had chances to win it but didn't take them."
Derby manager Frank Lampard on BBC One: "I'm delighted for the team and the squad. The workrate they put in there, having to come through VAR going against us in really small margins, they worked so hard and they were great penalties at the end and great courage from the lads.
"We've had two games against Southampton and a tough patch in the league, playing some really good teams, so the lads have been working so hard. It takes a lot to come back against Premier League opposition and show the fight and the bravery on the ball. I thought we were outstanding through the game. Some of the football in the first half was brilliant.
"It's a tough turnaround for the weekend and Accrington in the next round - it's the FA Cup, it's magical, look at the fans who have travelled. A big thank you to the fans. They're going to get back to Derby at whatever time and they're probably working tomorrow too so a big thanks to them because they helped us get over the line."
Wilson's free-kick threat - the stats
- Southampton have been eliminated from the third round of the FA Cup by a side from a lower division than themselves for the first time since 2001-02 when Rotherham United beat them 2-1.
- Derby County have now progressed from all three of their penalty shootouts in the FA Cup, all coming in third round replays (also against Sheffield Wednesday in 2007-08 and Millwall in 2009-10).
- Nathan Redmond has been directly involved in seven goals in his nine games under Ralph Hasenhuttl for Southampton in all competitions (five goals, two assists), as many as his last 63 appearances for the Saints combined before the Austrian's arrival.
- There were just 136 seconds between Stuart Armstrong opening the scoring and Nathan Redmond doubling Southampton's lead against Derby.
- Derby County's Harry Wilson has scored eight goals from outside the box in all competitions this season, at least twice as many as any other player in the top four tiers of English football in 2018-19. Five of those eight have been from direct free-kicks.
- Harry Wilson has had a hand in 14 goals across all competitions for Derby this season (11 goals, three assists), more than any of his team-mates.

I can't believe they are paid to make these pathetic comments.
Finally congrats to Derby, great comeback!
1. the Saints fans chanting VAR every decision, it's was embarrassing
2. Danny Murphy's inane 'commentary' he has such a boring voice, everything he says is so obvious, it really isn't an 'expert' opinion
3. The constant plugging of another channel, I'm fed up of brexit, I don't want to hear about it during a football game!
well played Derby, Lampard looks like he learned something from his uncle and Jose
blah blah.
Mate, you're 12th and going backwards. Both Birmingham and West Brom are above you.
Just for clarity...
hats off to derbys men and tactics after that .
frank must be really proud of his teams resolve.
you could see southampton wanted the next round
even though ,for survival purposes southampton
might benefit as to focus now solely on the prem .
hope frank and derby make the playoffs.
Now, congrats to Derby. A well fought victory.
Anyway, well done Derby. You look a very tidy team and, on the grounds you had the better of the first 45 & last 15 or so (ET was pretty even), I reckon you deserve it. Not by a lot, but enough!
Maybe the red line on VAR needs a yellow band either side representing the margin of error?
Southampton can now concentrate on staying, while Derby can bask in the glory of the cup, for a while.
Coming back from such a mountain to climb shows a good attitude.
Would have been nice at the end if the pundits had given some credit to the players who worked so hard, rather than just glorifying their studio pundit friend from the World Cup. It's a team game, Lampard would say it himself.
