Millwall have signed defender Karleigh Osborne on a free transfer from League one side Brentford.
The 24-year-old centre-half turned down a new deal at Griffin Park and has agreed a two-year contract with the Lions.
Osborne, who can also play at right-back, has been training with Millwall this week and will join them on their pre-season tour of Ireland.
He made 184 appearances for the Bees and scored six goals.
Lions full-back Tony Craig agreed a switch in the opposite direction earlier on Friday.
