Middlesbrough defender Justin Hoyte has begun training with Millwall ahead of a possible loan move to the South London club.
The 28-year-old has fallen out of favour at the Riverside Stadium this season, making just four appearances since the start of the campaign.
The former Arsenal full-back could soon sign a temporary deal at The Den as Lions boss Steve Lomas looks to boost his defensive options.
Hoyte joined Boro from Arsenal in 2008 following a loan spell with Sunderland.
