Seamus Coleman saw red for the visitors early in the second half following a barge on Dwight McNeil, which followed an accidental, but reckless first half challenge that ultimately forced Erik Pieters out of the game.
“Erik is ok, we think," said Dyche. “I don't think Seamus Coleman is that type of player, indeed I don't think there are too many of that type around anymore.
“But equally, that first challenge is still probably a red card. On reflection, when you see it, it doesn't look a good tackle, and even though he hasn't meant it, the referee's role is not to decide if it's an accident, but whether it's dangerous.
“I like a tackle, but once he's got the yellow for the first, I think the red for the second is inevitable."
