Millwall have signed defender Mark Beevers from Sheffield Wednesday on a 28-day emergency loan.
The 22-year-old centre-back has made seven starts for the Owls this season but lost his place after featuring in four consecutive defeats in September.
Kenny Jackett was in need of defensive cover with Paul Robinson injured, while Karleigh Osborne and Shane Lowry are suspended.
Tam Mkandawire is back in the squad after a year's absence due to a knee injury but Jackett felt it would be prudent to add further cover with Millwall currently in the relegation zone.
Despite his youth, Beevers brings plenty of experience having played more than 150 games for Wednesday since making his debut in January 2007 just months after turning 17.
