"Andy has not played for a while but he came in and did a fine job," said Coleman to the media.
"It was difficult for him, the last goal. It was a crowd of bodies and he saw it late. There was nothing he could do. "Keiren could not complete the warm-up. A dozen of them have been sick all night, so it has got to be something they ate yesterday."
He said: "The game plan was not to concede an early goal but that went out the window. They were pretty much the dominant team in the first half, so I was happy at 1-0.
"We changed our formation in the second half and we got better and better. I knew the Ewood Park crowd would get nervous if we managed to nick a goal and we put Blackburn on the back foot.
"To be 2-1 up with only a couple of minutes to go, it feels like a defeat. But we have managed to take them back to our place, which is something."
