Crystal Palace have signed defender Matt Lawrence from Millwall for an undisclosed fee. Lawrence has been with the Lions for the last six years.
The 32-year-old will link up with former Lions team-mate Darren Ward at Selhurst Park to become Palace's sixth summer signing.
Fitz Hall and Emmerson Boyce both left the club to join Premiership side Wigan this summer, leaving Peter Taylor's men short at the back.
