Steve Morison will join Sky Bet League One side Shrewsbury Town on loan for the duration of the 2019/20 campaign.
The Lions legend leaves the club having scored 92 goals in 335 appearances since initially joining from Stevenage in the summer of 2009.
Clocking in at equal-fifth in Millwall's all-time leading goalscorer chart - with just Wally Davis, John Calvey, Teddy Sheringham and Neil Harris above him - Morison's first season at The Den ended in promotion via a League One Play-Off Final victory over Swindon Town; but it wasn't all plain-sailing to begin with.
Having hit the back of the net just twice before December, questions were asked, however, a last-minute winner at home to MK Dons was to be the spark the attacker needed, going on to finish the campaign with 23 goals, including vital strikes against Charlton Athletic, Leeds United and Swindon along the way - not to mention the opener in the Semi-Final win over Huddersfield Town.
Morison's 17 goals in The Lions' first season back in the second tier proved that the jump was no problem at all, with the Welshman also receiving international honours and playing alongside names such as Gareth Bale.
A big-money move to Norwich City saw Morison taste Premier League football, but after 18 months at Carrow Road and a further six at Leeds United, the striker returned to The Den on loan for the 2013/14 campaign - eight goals were scored as The Lions managed to stay in The Championship.
After a year at Leeds, Morison found himself back in SE16 for a third time as Harris, now manager, signed the frontman on a permanent basis.
Forming a deadly partnership with Lee Gregory, Morison struck 19 times as Millwall made the League One Play-Off Final, but were unfortunate losers to Barnsley at Wembley Stadium. The Lions returned to North London 12 months later, however, to put things right, defeating Bradford City 1-0 - and it was Morison who dealt The Bantams the decisive blow with a late winner to spark wild celebrations. The Player of the Year scored 19 times once more, including a double in the Semi-Final success at Scunthorpe United, as the club would taste Championship football again.
With his career advancing, Morison's playing style adapted from an out-and-out goalscorer to an even more savvy, intelligent and integral member of Harris' squad, and despite only finding the net five times, the 2017/18 campaign was a fine one for the attacker as Millwall finished eighth, just missing out on a shot at the Premier League.
Morison 92nd and final Millwall goal was the winner in a 2-1 Den victory over Wigan Athletic on 23rd October 2018.
Off the field, the 35-year-old also acted as the club captain and was recognised for his outstanding work in the community by being named PFA Community Champion of the Year at last season's End of Season Awards Night, whilst he is also an Ambassador for Show Racism the Red Card.
There is simply no denying that Steve Morison is a Lions legend.
Everyone at Millwall would like to wish Steve the very best during his spell at Shrewsbury.
