Boss Gary Bowyer saw his side do everything but score as they had to settle for a point against Huddersfield Town.
In a repeat of last season's goalless draw, the visitors had goalkeeper Alex Smithies to thank as his string of second half saves kept Rovers at bay.
Bowyer was pleased with the way his patched up side approached the match, but disappointed that they couldn't claim all three points their play deserved.
"Anybody who has watched that game today will be going away from here wondering how we haven't won it," Bowyer told Radio Rovers after the match.
"Their goalkeeper has been magnificent for them in the second half. King has had chances, Jordan has had chances, Grant Hanley has had great opportunities from set-plays, Lee Williamson has a fantastic strike but the goalie pulls out a hell of a save.
"We had to respond and I think the people of Blackburn will see that they've responded. These lads care, the size of the squad was tested severely today but the lads that came in were terrific."
Rovers had a great chance to claim all three points but the usually prolific Jordan Rhodes was off target with a 61st minute penalty.
"How many games has he won us in the past and will win us in the future?" added Bowyer. "He's disappointed in there for sure, but he'll bounce back and score loads of goals this season, I've no problem with that.
"In terms of the number of chances that we are creating and the style of football we are playing, we are more than happy with that.
"But, we do need to be a little bit more ruthless."
