Derby County sealed a Championship return by beating already-relegated Carlisle United 2-0 at Pride Park on the final day of the League One season.
Derby knew a single point would end their two-year stay in the third tier of English football, with Bolton Wanderers waiting to pounce if the Rams did suffer a shock defeat.
However, such a slip-up never looked likely as Max Bird s powerful strike from outside the area put them ahead within five minutes, and James Collins added a close-range second on the hour mark to make certain of promotion.
Paul Warne s team finished five points behind Portsmouth, who clinched the title earlier this month, and five clear of Bolton – who needed a late equaliser from Cameron Jerome to draw 3-3 with Peterborough.

Bolton will face Barnsley in the play-offs as the Tykes were not punished for their 1-1 draw with Northampton Town, defeats for Blackpool and Lincoln City denying them the chance to gatecrash the top six.
Fourth-placed Peterborough will face Oxford United in the other play-off semi-final, as the U s clinched a 2-1 win over Exeter City to claim fifth place in the final reckoning.
Three of the four relegation places had already been decided before Saturday s matches, with Carlisle, Port Vale, and Fleetwood Town on their way to League Two.
Cheltenham will join them after Nick Freeman struck a 90th-minute winner in their 2-1 loss at Stevenage. Darrell Clarke s side needed a win to save themselves and send Burton Albion down in their place, but they were hit with a late sucker punch as their three-year stay in League One came to an end.
