Herbie Kane is 20/1 to repeat his antics from last Sunday's game against Chorley by hitting a brace in Tuesday's replay.
The on-loan Liverpool man scored his first two goals for Rovers in the original tie at Victory Park - he is 3/1 with EFL title sponsors Sky Bet to get on the scoresheet again with at least one goal, and 20/1 to again get a double.
Rovers are 1/9 to progress to a second round tie against Mansfield Town or Charlton Athletic, and 1/4 to secure victory inside 90 minutes.
It is 17/4 for the tie to go to extra-time, and 10/1 for the Magpies to claim victory in normal time at the Keepmoat Stadium.
