Manager Paul Dickov spoke to Rovers Player after the defeat at the Reebok.
He said; "I think we dropped way below the standards that we have set ourselves recently.
"Bolton came out on the front foot and we sat off them way too much, especially in the first half. The game was being played in one half early on. Overall, we looked a little bit leggy and half a yard short.
"I'm not going to say that we deserved to get anything out of the game because we didn't. Maybe it might have been that we have had five games in fourteen days with the same group of players, maybe it could had been one game too far in a short space of time with a small group.
"We are striving to get consistency, not just results but performances as well. We just have to keep positive.
"I believe we have a good bunch of players here, once we start getting players back and get a full squad we will be able to get more consistency."
Dickov was asked about players coming back and added; "We are hopeful that Yun will be back with us Thursday, which will give us another option as he doesn't just play left back.
"The massive bonus today was getting Chris Brown back. Chris came to see me yesterday and begged me to put him on the bench, that is the sort of attitude you want."
