Mallik Wilks continued his remarkable start to life at Rovers with his third goal in as many games as he helped his side into the second round of the Carabao Cup.
Wilks' first-half effort, coupled with a stunning Danny Andrew effort, was enough to seal victory at Glanford Park despite a late consolation from the home side.
Rovers are back at the Keepmoat Stadium on Tuesday August 21 to take on John Askey's Shrewsbury Town in Sky Bet League One, get your tickets now from tickets.clubdoncaster.co.uk.
