Millwall have completed the signing of Justin Hoyte from Middlesbrough on an emergency loan deal.
The 28-year-old defender, who began training with the club on Monday, will remain at The Den until January 1.
"I'm looking forward to it. It's a new challenge for me," Hoyte told Millwall's official website. "My family is here in London so that's good to get back here."
Millwall return to Championship action on Saturday when they make the trip to Bolton Wanderers.
