Burnley secured an immediate return to the Premier League, with Josh Brownhill's brace sealing a 2-1 victory over Sheffield United at Turf Moor.
The Clarets' skipper scored twice in the first half as Scott Parker's side assured their place in the automatic promotion places, while ensuring the Blades would have to settle for a play-off spot.
The win means Leeds United, who thumped Stoke City 6-0 earlier on Monday, will join Burnley back in the top flight, with both sides now eight points clear of Chris Wilder's team with two matches remaining.
The hosts broke the deadlock in the 28th minute, as Brownhill fired into the roof of the net from close range after Michael Cooper could only parry Josh Cullen's initial attempt.
United were back on level terms nine minutes later with Gustavo Hamer embarking on a strong run into the box before feeding Tom Cannon, who rifled the ball past James Trafford from a tight angle.
However, Burnley regained their lead just before half-time; Brownhill calmly sending Cooper the wrong way from the penalty spot after Anel Ahmedhodzic fouled Hannibal Mejbri in the box.
It proved to be enough at Turf Moor, as Parker's side held out to spark wild celebrations among the home supporters, with Premier League football set to return next season.
Data Debrief: Burnley break club record thanks to penalty king Brownhill
As well as sealing a top-flight return, Burnley extended their unbeaten league streak to a new club record of 31 matches.
The Clarets have won all 18 of their Championship matches this season in which they have led at half-time.
Fittingly, top scorer and captain Brownhill sealed the victory, taking his tally for the season to 16 league goals. He has also now scored a joint league-high three penalties this term, level with Portsmouth's Colby Bishop.
Three is also the magic number for Parker when it comes to winning promotion from the Championship, which he has secured with three different clubs (Fulham in 2019-20 and Bournemouth in 2021-22).
