Aston Villa defender Nathan Baker has joined Championship strugglers Millwall on a one-month loan deal.
The 20-year-old England Under-21 international, who had a loan spell at Lincoln, predominantly plays at centre-half but can also fill in at left-back.
He has made five senior appearances for Villa but is yet to feature under new manager Alex McLeish this season.
Millwall are 20th in the Championship table, just two places above the relegation zone.
Baker signed at the start of June.
