After a 3-1 win over West Ham United at LCFC Training Ground last time out, the Foxes youngsters followed it up with their first success on the road, taking another three points from their trip to the County Ground.
Centre-back Paul Appiah scored his first-ever Leicester goal to give the visitors an early lead just two minutes into the contest and the uphill battle for Blackburn worsened half an hour in when Jake Batty was sent off.
Making their numerical advantage count, Kasey McAteer added a second for the away side almost immediately after the red card.
It took another five minutes to take the game further away from Rovers, with Joe Wormleighton the latest City player to net for the first time this season.
The fourth arrived in first-half stoppage time, as Tawanda Maswanhise continued his record of striking in every league fixture this term. The forward’s fourth of the campaign rounded off the scoring in Leyland.
The result sees the team coached by Ben Petty move up to sixth in Premier League 2 Division 1, with seven points from four games, while the Lancashire side remain rooted to the foot of the table, yet to register a point in 2022/23.
City turn their attention to the Papa John’s Trophy on Tuesday, facing Sky Bet League 1 side Burton Albion at Pirelli Stadium in their first Northern Group H fixture (7pm kick-off), while next up in PL2 is a meeting with Brighton & Hove Albion Under-21s in Seagrave on Saturday (1pm kick-off).
