The Premier League will welcome Watford next season after they beat Brighton and Hove Albion 2-0, before Middlesbrough lost a seven-goal thriller to Fulham and Norwich City were held by struggling Rotherham United - both of those matches featuring late drama.
Goals from Troy Deeney and Matej Vydra ensured Slavisa Jokanovic's men did their bit in one of two early kick-offs in Saturday's Championship action, while results went their way later in the afternoon.
Their return to the top flight after an eight-year absence was confirmed after Fulham scored deep into stoppage time to beat Middlesbrough 4-3, while Norwich conceded an 86th-minute equaliser in a 1-1 draw that kept Rotherham - deducted three points in midweek for fielding an ineligible player - out of the bottom three.
Middlesbrough - who had fought back from 3-1 down to level it up, despite George Friend's dismissal - sit third, level on points with Bournemouth, who play their game in hand against Bolton Wanderers on Monday and have a far superior goal difference.
Freddie Sears' late winner gave Ipswich Town a 2-1 success against Nottingham Forest that leaves Mick McCarthy's men needing a point against Blackburn Rovers on the last day to seal a play-off position.
Bottom side Blackpool were beaten 3-2 at mid-table Cardiff City, and Huddersfield Town came from two goals down to claim a 2-2 draw at home to Blackburn - Jordan Rhodes on target against his former club.
