Brighton sealed promotion to the Premier League and increased their lead at the top of the Sky Bet Championship to seven points with a 2-1 win over Wigan at a jubilant Amex Stadium.
The squad conducted an impromptu party on the pitch at full-time, although promotion wasn't mathematically confirmed until Huddersfield dropped points at Derby in the late game.
Glenn Murray opened the scoring for Chris Hughton's side eight minutes before half-time, his 22nd goal of the campaign and fifth in as many games at the Amex Stadium.
England Under-21 international Solly March ensured the celebrations could continue in earnest when he converted Anthony Knockaert's cutback and a late goal from substitute Nick Powell could not change the picture.
Newcastle, league leaders for so long, slipped to seven points behind the Seagulls as they took their winless run to three matches with a 3-1 reverse at Ipswich.
Freddie Sears put the hosts ahead just before half-time, but when former Tractor Boy Daryl Murphy levelled in the second half the Magpies had a chance to switch their fortunes.
Instead they conceded twice more, David McGoldrick and Emyr Huws the scorers.
Huddersfield looked set to delay - technically at least - Brighton's promotion and keep the pressure on Newcastle when they led at Derby through Colin Quaner, but a late deflected strike from Jacob Butterfield earned the Rams a 1-1 draw that will have been cheered on both Tyneside and the south coast.
Huddersfield are now seven points adrift of Newcastle with a game in hand, and five points clear of seventh.

Wednesday won by the same margin at QPR, Adam Reach and and Daniel Pudil notching either side of Idrissa Sylla's equaliser.

Ryan Sessegnon gave the Cottagers the lead after hitting the crossbar and, although Jack Grealish restored parity following Jonathan Kodija's red card, the result never seemed in doubt.
Sone Aluko and Neeskens Kebano settled matters as the numerical disadvantage came to bear in the second period.
All of that spelled bad news for Garry Monk's Leeds, who were turned over at Elland Road when Wolves striker Nouha Dicko grabbed the only goal of the game.
Blackburn salvaged a draw from Bristol City's trip to Ewood Park, Sam Gallagher cancelling out Tammy Abraham's effort, but they remain third bottom and deep in trouble.
Norwich defeated Preston 3-1 at Deepdale, but neither side can now hope to crack the play-offs.
Graham Dorrans and Josh Murphy gave the Canaries a first-half cushion before Tommy Spurr and James Maddison traded strikes.
Burton gave their survival bid a boost and leapfrogged Birmingham in the process thanks to a 2-0 triumph built around goals from Lloyd Dyer and Lucas Akins.
Aron Gunnarsson gave Cardiff a 1-0 win over struggling Nottingham Forest and Brentford drew 1-1 at Barnsley as Florian Jozefzoon and Marley Watkins scored.
