Tony Mowbray was satisfied with the fitness workout, but disappointed with Rovers' lack of cutting edge, in Saturday's 1-1 draw against Port Vale.
In a game of few chances, the hosts were handed the lead when Charlie Mulgrew inadvertently headed past Andy Fisher early on.
Rovers equalised at the midway point in the first half when Darragh Lenihan powerfully headed home Craig Conway's corner.
Despite dominating possession for large periods, the visitors failed to find a second goal, with Willem Tomlinson and Joe Rothwell going closest after the break.
With Danny Graham missing due to a slight knock, Rovers were short of numbers in the attacking areas, but Mowbray insists the club are working hard behind the scenes to introduce some fresh faces to the squad.
"It was alright," was the Rovers boss' honest assessment after the game.
"It was another hot day. It was a big pitch, which was important, so that we could get the physical aspect out of the game.
"Everybody that was here got more gametime, so in that context it was alright.
"It was a different type of game for us. We played against a team with big centre forwards who banged it off the front and played off second balls, which is a bit different from what we've been playing against or how we play in training, but there's going to be teams in the Championship who play very direct as well, so we have to deal with that.
"We didn't control it as much as I would have wanted, particularly in the first half. In the second half, we had a lot of control, but no shots really.
"I have to say we were short of strikers. I couldn't give 90 minutes to [Dominic] Samuel, because he missed the Hibs game, but he did need to get some gametime.
"Danny Graham was obviously missing, so we didn't have the rotation of the front players. Bradley [Dack] came off after 60 minutes, so ultimately that explains why we didn't have enough cutting edge in a game where we had lots of the ball, but no shots really.
"So that was a bit frustrating, but we are working hard behind the scenes to try and add some reinforcements in that part of the pitch.
"I am pretty confident that we will have reinforcements over the next few weeks."
