The Seasiders leap-frogged their visitors in the middle of the Championship table courtesy of Ludovic Sylvestre's stunning strike shortly before the hour mark - but Dyche insisted the game could have gone either way on a poor pitch.
He said afterwards: "On that surface it was either probably going to end up as a mistake from someone or a quality finish.
"It was a tight affair. They had the better fist of it the first 25 minutes but I actually thought they managed to play on that surface.
"We had pockets of it as the half went on, their keeper made a brilliant save against Wallace which is the best I've seen for quite some time.
"(In the) second half the quality softened because of the pitch - which is the worst I've ever seen in my career and I've played on some bad ones, I can assure you.
"I'm absolutely sure Paul Ince wants to play on a better surface than that but it is what it is - there are no excuses, I want to make that clear."
