Former Brentford defender Karleigh Osborne has completed his move to Championship side Millwall on a free transfer.
Sky Sports revealed earlier on Friday that the centre-half was set to link up with the Lions.
Osborne has penned a two-year contract at The Den after seeing his deal with the Bees run out.
He spent eight years at Griffen Park, during which time he made 184 appearances and scored six goals.
Millwall offered him an opportunity to impress during a trial spell, and Kenny Jackett liked what he saw.
Osborne, who is also capable of operating at right-back, will now join up with the Lions on their pre-season tour of Ireland.
