Byron Webster has left Millwall after his contract was cancelled by mutual consent.
The 31-year-old has signed for Sky Bet League One side Scunthorpe United for the rest of the season.
The defender departs the club having made 137 appearances and scoring eight goals since his arrival from Yeovil in the summer of 2014.
Webster made his debut for The Lions against Wycombe Wanderers in the Capital One Cup and appeared in the League for the first time three weeks later as Blackpool were defeated 2-1.
A difficult start to the centre-back's Millwall career meant a loan move back to Huish Park in January 2015, but the former Doncaster man returned to The Den for the start of the 2015/16 campaign and became an integral part of a side that reached the League One Play-Off Final, playing 50 times, scoring six goals - his first for the club coming in a 5-3 defeat at Peterborough United.
As The Lions went one better in 2016/17, so did Webster, as he made 55 appearances in a campaign which saw Neil Harris' side win the Play-Offs, defeating Bradford City in the Final.
Webster's Championship charge was to be cut short in September 2017, however, as he suffered a serious knee injury in a 3-1 loss to Barnsley at The Den. The 31-year-old recovered, though, and has made six appearances so far this season, with the last coming as a late substitute in the New Year's Day victory at Ipswich Town, but he will now seek pastures new for the rest of the year.
"Webby will be a big miss," Neil Harris told millwallfc.co.uk. "He's had a tough 17 months after his cruciate injury last season, but the way he was in his rehab, his professionalism, his dedication, was a lesson to all of us to learn from.
"There was great satisfaction in him signing a new deal in the summer, and then coming back on to the pitch again. Opportunities have been limited for him this year, and it's come to a stage now where he is in his 30s and needs to play football.
"He has been great on and off the pitch, I've really enjoyed working with him. He's a total professional, I can't praise him enough. He goes with our blessing, and Scunthorpe have got a very good player on their books."
The club would like to thank Byron for his outstanding efforts whilst with Millwall and wish him all the best for the future.
