Millwall have signed Nottingham Forest defender Dan Harding on loan until the end of the season.
The 31-year-old trained with his new teammates for the first time on Monday morning.
Harding, who can count Leeds United, Ipswich Town and Southampton among his former clubs, is due to be out of contract at the City Ground in the summer.
Millwall continue their Championship campaign on Saturday when they make the trip to Blackpool.
