Leeds head to familiar territory in Rovers’ Keepmoat Stadium, a venue where they have not lost in six visits, winning five, with Doncaster having not triumphed against them in all competitions on home soil since way back in August 1951.
United will make the short trip down the A1 in the competition for the third time in four years this August, having triumphed 3-1 in a second-round clash there in August 2013, thanks to goals from Scott Wootton, Matt Smith and Ross McCormack.
Two years earlier at the same stage of the competition, a Ramon Nunez brace saw Leeds prevail 2-1.
Meanwhile, 2012-13 finalists Bradford City will travel to Bootham Crescent in another all-White Rose clash at York City, who have not won a League Cup tie since 1997-98.
The Bantams’ last visit to York in March 2013 proved a fateful one, with then Minstermen manager Gary Mills sacked shortly after the visitors’ 2-0 win, thanks to goals from James Hanson and Garry Thompson.
Huddersfield Town, Rotherham United and Sheffield Wednesday have also been afforded home comforts in the first-round.
Town will play host to Notts County, while the Millers entertain Cambridge United.
Wednesday welcome Mansfield, who return to the Steel City in the first round for the second successive season, having lost at Bramall Lane last term.
Middlesbrough have been handed a trip to Oldham for the second successive season, having triumphed 3-0 at Boundary Park in round one in 2014-15.
Barnsley make the trip to Scunthorpe United, managed by former Reds manager Mark Robins, while last season’s semi-finalists Sheffield United face a potential banana-skin tie at Morecambe.
Relegated Hull City have also been handed a tricky assignment in the north-west at Accrington Stanley.
All ties will be played in the week commencing August 10, 2015.
