Wigan's relegation was confirmed with defeat at Reading on Saturday, but the fight for Championship survival will go down to the final day.
Yann Kermorgant's early goal at the Madejski gave Reading a 1-0 win which rubber-stamped a Wigan relegation that was as good as certain before kick-off.
Elsewhere, already-promoted Brighton missed the chance to secure the Championship title after slipping to a 1-0 home defeat to Bristol City.
Josh Brownhill's goal shortly before half-time was enough to secure the Robins all three points at the Amex Stadium, a win that confirmed their survival.
But there will be no shortage of drama at the bottom next Sunday, with Blackburn, Nottingham Forest and Birmingham all in danger of the drop.
Forest's goal difference is one better and they finish the season with a home game against Ipswich next Sunday, while Blackburn are away at Brentford.
Birmingham are two points better off than their rivals thanks to a 2-0 win over much-changed Huddersfield achieved despite the early dismissal of Che Adams.
Adams was given a straight red for a foul on Martin Cranie shortly after Lukas Jutkiewicz had missed a penalty for Blues, but goals from Jonathan Grounds and Craig Gardner gave Harry Redknapp a first win ahead of next week's trip to Bristol City.
Barring an outlandish set of results Fulham will finish sixth, despite their failure to beat Brentford at home.
Nico Yennaris answered Tom Cairney's early goal, but Leeds could not quite pull off a remarkable comeback at Elland Road having gone 3-0 down to Norwich.
Goals from Chris Wood, Kyle Bartley and Pablo Hernandez levelled the scores, but even Steven Naismith's late red card for the visitors failed to bring a Leeds winner.
