Dan McNamara has joined Vanarama National League outfit Dover Athletic on a 28-day loan deal.
The 20-year-old defender, who has been a regular for Kevin Nugent's U23 side for The Lions this season, will spend the next few weeks with Andy Hessenthaler's squad for his first taste of National League experience.
McNamara previously enjoyed a month-long spell with Welling United in the National League South, and will now have the opportunity to test himself in non-League's highest tier.
Everyone at Millwall would like to wish Dan all the best during his time at The Crabble with Dover Athletic.
