Millwall right-back James Brown has joined Scottish Premier League side St Johnstone on loan until the end of 2020/21 season.
In return, Danny McNamara has been recalled from his loan spell at Callum Davidson's outfit.
Brown, who regularly captains Millwall's Under 23 side, will - subject to international clearance - spend the rest of the campaign at McDiarmid Park and hope to make his debut in next Saturday's trip to Dundee United.
McNamara, meanwhile, returns to South London having undergone a successful spell north of the border - making 21 appearances and scoring one goal - and will now be looking to break into Gary Rowett's first-team squad, beginning with this weekend's Emirates FA Cup Third Round tie at Boreham Wood.
