Darragh Lenihan felt Rovers didn't get the rewards that their desire and determination deserved as they slipped to a narrow 2-1 loss at home to Preston North End.
Rovers started strongly in front of the largest crowd of the season Ewood Park, taking the lead on the 13th minute when Elliott Ward blasted home after Hope Akpan had headed against the crossbar.
But the sending off of Shane Duffy for handling on the line changed the match as the visitors converted the penalty and then took the lead just before the break.
Despite being a man light Rovers gave their all in the second half, but they just couldn't find the equaliser their play merited.
"It was very frustrating considering the effort that we put in," Lenihan told Radio Rovers.
"It is disappointing after I felt we controlled the game for the first 20 minutes until they got the penalty and Duffy got sent off.
"But we'll have to learn from that, we thought it might have been something similar to Brentford when we had Grant sent off, we just kept believing and kept working hard, but in the end it didn't work out.
"It was tough, we tried to stay in the game but then they score the second goal which was disappointing.
"We came out in the second half, we changed our shape and we got a little bit more joy, we had a few more chances but it just wasn't our day.
"We'll move on, we'll put this behind us and focus on Sheffield Wednesday now."
