Both of Dagenham's FA Cup ties this season have gone to extra time in a replay.
Millwall's loss to Birmingham last season was their first defeat in normal time on home soil in the FA Cup since 2003.
The Lions are unbeaten in 15 FA Cup games (including replays) against lower league opposition, a run that stretches back to a 0-1 defeat at Hartlepool in October 1999.

The Trotters have kept six clean sheets in their last eight FA Cup game against lower ranked sides.
Macclesfield have never made it past the third round of the competition, losing all eight previous third round games before their draw against Bolton this season.
