Tony Mowbray lamented costly errors as his side slumped to a 3-1 home loss to Doncaster Rovers.
After a goalless first, a mistake by Elliott Ward lead to John Marquis opening the scoring, before James Coppinger converted from the spot after he was adjudged to have been brought down by Charlie Mulgrew.
As Rovers struggled for a way back into the match they conceded a sloppy third. David Raya gifting the ball to Alfie May who slotted it home.
Dominic Samuel did bag his second goal in successive matches three minutes from time, but it was mere consolation.
"There are no excuses, we gave some dreadful goals away," Mowbray told iFollow Rovers after the match.
"We were frustrated in the first half, we had one or two good opportunities to score and give ourselves a chance to play how we would like to play.
"But we missed a couple of chances first half and then shot ourselves in the foot right at the second.
"I don't think you can say it was bad play or anything to do with the team it was an individual error that cost us the goal. Then after the penalty the game ran away from us.
"It isn't a day for making excuses, it's not a day for anything other than the feeling of disappointment and frustration for the supporters who have had to deal with it for a long time.
"We have to put it behind us very quickly and get ready for the next one."
