On an enthralling Friday packed with Championship action, Bolton's relegation to League One was confirmed with a 2-0 loss to Aston Villa.
The Wanderers, who have struggled for much of the season with the club in financial turmoil, will play in England's third tier seven years after their drop into the Championship from the Premier League.
Villa, who sent Bolton down thanks to goals from Jack Grealish and Tammy Abraham, equalled a club record run of nine straight league wins on Friday and are all but certain to feature in the play-offs.
