Damien Johnson felt that Rovers performed admirably as they went down 1-0 to Notts County on Sunday.
With the seniors playing against Girona at Ewood on Saturday, it was the turn of the younger players at Meadow Lane 24 hours later.
A first half goal from Adam Campbell settled the friendly match in the home side's favour, but despite the result Johnson thought the young Rovers stood up to the challenge of the League 2 club.
"It was a pleasing workout and it was a tough test for our lads," Johnson told Rovers PlayerHD.
"We knew they'd be strong, they are a league side that are a week off their season starting so it was going to be a good challenge and a test the young boys.
"For the most part I thought they stepped up and acquitted themselves well, obviously we are disappointed to lose the game and there are things to learn from it, but overall it was pleasing.
"They are a proper league side with some good players and they put us under a bit of pressure, but I felt we coped quite well with the physical side.
"We were probably a little bit naive for the goal and on a couple of occasions, but that is just part of their learning so they've got to learn from that today and hopefully improve on that for the next step."
