Millwall have signed Owen Garvan on loan from Crystal Palace until the end of the season.
The midfielder, 26, has made 86 appearances for the Eagles since joining from Ipswich in 2010 but has found first-team opportunities at Selhurst Park limited so far this season.
"Millwall are in a bit of a difficult situation, but hopefully I can help play my part in turning the results around," the Irishman told the Lions' official website.
"As a professional player you can't beat that feeling of playing on a Saturday and picking up three points, and that's what I'm here to achieve.
"I've played at The Den with Crystal Palace so I know how big a factor our home fans can be. We've got Brighton on Saturday and it's important we start on the front foot."
