STEVE Morison is leaving the Lions to join League One Shrewsbury Town on a season-long loan deal.
Morison, 35, has one year left on his deal with Millwall, but looks to have played his last game for the club, one short of 200 in his third spell at The Den.
Morison links up with Shrews boss and former Wales team-mate Sam Ricketts.
Morison's top five moments
The 31-year-old centre-forward made a third Lions 'debut' in glorious sunshine at Greenhous Meadow on the opening day of the 2015-16.
After Shrewsbury took the lead, Morison equalised before strike partner Lee Gregory netted the winner from the penalty spot to give Neil Harris three points in his first game in charge in League One.
Millwall reached the play-offs that season and went to Valley Parade for a tough looking semi-final first leg.
Bradford went in front but the Lions responded in brilliant fashion and Morison was central to the comeback. He nodded down for Gregory to level before heading home to put Millwall 2-1 before Joe Martin's free-kick made it three.
Millwall drew 1-1 in the return leg to reach Wembley, where they lost 3-1 to Barnsley.
Harris' side were back in the play-offs the following season, and after a 0-0 draw at The Den Scunthorpe were favourites to go through at Glanford Park, especially after going 1-0 up.
But the game was turned on its head when Morison used his to nod in Tony Craig's cross and then set up Gregory for the second. Morison added the third and though the Iron scored late the Lions hung on for another Wembley date.
Morison's finest moment in a Millwall shirt?
As well as being on the losing side the previous year, Morison had had the armband taken off him when Byron Webster was injured in the warm-up and Craig led the side out.
It stung, but Morison put it behind him and was the joint-leading scorer with Gregory the next season ahead of the decider against Bradford.
With five minutes left, Shaun Williams wearily crossed from the left, Gregory glanced on a header, and Morison stole in behind Nathan Knight-Percival for his 19th goal of the season and the one that returned Millwall to the Championship.
Millwall lost two and drew two of their opening four league games of the 2017-18 season before Morison's former club Norwich visited The Den.
Morison was imperious, setting up the first for Gregory in a 4-0 win.
That stylish victory gave the side confidence they could compete in the second tier and they went on to finish eighth, three points off the top six.
