Former Gillingham boss Andy Hessenthaler has gone back to Priestfield to secure the loan signing of Ryan Huckle from the League One side.
The recently installed Dover Athletic manager finds his side bottom of the National League and seven points adrift of safety.
Huckle, 18, can play at centre-back and also in a defensive midfield role.
He joins Dover until December 1 and is eligible to play in Saturday's important clash against Maidenhead United at Crabble.
The Whites have not won in the league since August 14 while Maidenhead have shipped 13 goals in their last two matches.
