Paul Lambert couldn't fault the player's efforts but felt that the exploits of the last month caught up with Rovers as they went down 2-1 at home to Leeds United.
Rovers started strongly at Ewood Park but goals from Sol Bamba and Mirco Antenucci put them on the back foot.
Simeon Jackson gave the home side hope with his first Rovers goal but it proved to be mere consolation.
"I don't think we deserved to lose," the manager told Radio Rovers.
"I thought we started the game really well but against the run of play they scored from a corner, and then from our own corner they break and get a second.
"But the fixtures we had, and the gruelling timescale to turn around games, has been extraordinary and we've got another one on Tuesday.
"So I thought maybe it was a game too far in certain areas but that is not to fault the effort, drive and commitment. We made a right good fist of it and I still thought we were the better side.
"It wasn't for the lack of trying, sometimes you get the break of the ball and sometimes you don't, I couldn't ask for any more."
Rovers are back in action this Tuesday night when they travel to Portman Road to take on Ipswich Town.
