Wolves secured the Coca Cola Championship title on Saturday after a late Kyel Reid strike gave them a 1-1 draw at Barnsley.
It had looked as if the Wolves supporters would have to put the champagne on ice after Jonathan Macken put Barnsley a goal up early in the second half.
But Reid's equaliser six minutes from time secured the point Mick McCarthy's side needed to ensure they return to the Premier League as champions and kept the Tykes hovering just above the relegation zone.
Sheffield United beat Swansea 1-0 to temporarily close the gap to a point on second-placed Birmingham in the race for the other automatic promotion place. The Blues can secure their own return to the top flight with victory over Preston in the late kick-off, but Kevin Blackwell's side kept up the pressure thanks to David Cotterill's first-half penalty.
Roy Keane made the perfect start in his first game in charge of Ipswich, the Tractor Boys running out 3-0 winners at Cardiff. Richard Wright saved Ross McCormack's penalty in the 12th minute and things got better and better for Keane from there, Pablo Counago (34), David Norris (51) and Jonathan Stead (90) sealing a result which means that the Bluebirds' play-off spot is still not entirely safe.
Burnley retained the last play-off place after a 2-2 draw at Southampton, a result that confirmed the Saints' relegation and means they will be docked 10 points at the start of their League One campaign next year.
Bradley Wright-Phillips put the hosts a goal up in the 11th minute and after Graham Alexander had equalised from the penalty spot, David McGoldrick restored the Saints' lead a minute before half-time. But Clarke Carlisle's second-half strike ensured that Southampton's terrible season finished in disappointment.
Nottingham Forest remain in trouble after their former striker Brett Ormerod scored an equaliser for Blackpool in a 1-1 draw in the day's early kick-off. Dexter Blackstock put Forest ahead in the ninth minute but Ormerod levelled on the half hour, and despite having Ian Evatt sent off midway through the second half, Blackpool hung on.
Plymouth are only a point above Forest after a goalless draw at QPR, but Derby can breathe a little easier after Rob Hulse secured them a 1-0 win over relegated Charlton.
Elsewhere, Coventry threw away a 2-0 lead and had a man sent off in their 3-2 defeat to Watford at the Ricoh Arena, Lee Johnson, son of the manager Gary, scored for Bristol City in their 1-1 draw against Sheffield Wednesday and Doncaster defeated Crystal Palace 2-0.
