Millwall have signed left-back Matthew Briggs on a one-year contract following his release by London rivals Fulham.
The 23-year-old became the Premier League's youngest ever player when he debuted for the Cottagers in May 2007, but he rarely got another first-team chance.
He went on to make only 29 appearances over the next six seasons for the Whites, and was loaned out to Leyton Orient, Peterborough United, Bristol City and Watford before his contract expired at the end of last term.
The Lions offered him a trial earlier this summer and Briggs has now earned himself a 12-month deal.
Briggs is a former England Under-21 international.
