Wednesday defender Mark Beevers will complete a permanent transfer to Millwall when the transfer window opens in January.
The Barnsley-born player is currently enjoying a successful loan spell with the Lions but will make the deal a permanent one on January 1.
The Owls have agreed a transfer fee with their Championship rivals and Beevers has also agreed personal terms over a deal to move to the New Den.
Beevers, who came through the Wednesday youth set-up, moved to Millwall on-loan in October and has played for them eleven times, helping them climb up the Championship table.
