Defender Murray Wallace joined Millwall on a free transfer from Scunthorpe United in June 2018.
Able to operate at centre-back and left-back, the 25-year-old Scot started his career at Falkirk before making a £300,000 move to Huddersfield Town in 2012.
Wallace spent four years with The Terriers before moving on to Glanford Park, where he became a fans' favourite, making over 100 appearances.
The defender will challenge Jake Cooper, Shaun Hutchinson and Byron Webster for a centre-back berth in 2018/19.
