Millwall were defeated 1-0 by AFC Bournemouth on the final day of the 2021/22 Sky Bet Championship campaign.
Kieffer Moore's 81st-minute strike saw The Lions slip to a loss, finishing ninth in the League table.
Gary Rowett made one change to his starting XI for the trip to the Vitality Stadium, with Mason Bennett replacing Tom Bradshaw, who dropped to the bench.
Jed Wallace, meanwhile, took a place among the subs for the second consecutive matchday.
In a typically nervy affair, The Lions saw a lot of the ball but were unable to find any killer pass to unlock the Bournemouth defence - the first opportunity of the afternoon actually going to the home side on 11 minutes as Jaidon Anthony fired wide.
Robbie Brady and Emiliano Marcondes traded efforts as the half wore on, before Dominic Solanke's shot was blocked by Jake Cooper at the midway point of the half.
On 33 minutes came the biggest chance to date, however, and it went to The Lions. As George Saville crossed from the left, his pass was met by the head of Shaun Hutchinson, but the defender headed over the crossbar.
Half-hearted appeals for a Millwall penalty at the beginning of the second-half as Saville tumbled were turned away by Andre Marriner, before Jordan Zemura's cross agonisingly flashed across the face of goal on the hour-mark as The Cherries looked for the opener.
On 62 minutes, Bournemouth had the ball in the net, but Marcondes' strike was ruled out for offside. Saville and Oliver Burke then had efforts on goal as The Lions looked to open the scoring, but to no avail, but The Cherries did break the deadlock nine minutes from the end as Moore was left in a one-on-one situation to fire past Bialkowski.
Burke and Maikel Kieftenbeld tried to get Millwall back in the game in its dying embers, but The Lions were defeated at the Vitality Stadium.
