Sean Dyche described Hal Robson-Kanu’s controversial roughing-up of the penalty spot as “unacceptable” following the 0-0 draw at Reading.
The Welsh striker escaped with a yellow card for unsporting behaviour after running his studs over the spot following the controversial spot-kick award for a foul on Andre Gray by goalkeeper Ali Al-Habsi.
After a lengthy delay, Gray saw his resulting second half penalty saved by the Omani international.
And Dyche later insisted Royals striker Robson-Kanu had pushed gamesmanship too far.
The Clarets boss said: “I have only seen it (the penalty incident) live and it looks like a penalty to me from where I am.
“The melee afterwards can sometimes happen in games, but their player (Robson-Kanu) then kicks up the penalty spot
“That’s something I have never seen before in a football match and I hope never to see again.
“I would certainly not want my players conducting themselves in that manner. It’s unacceptable. It’s as simple as that.

“That is pushing gamesmanship too far for me and I don’t know what their view of it would be, but if I saw one of my players doing that, then I would make sure they knew that’s not how we go about our business.”
On the penalty itself, Dyche added: “I’m almost sure the goalkeeper then comes off his line before Andre hits it and that’s another detail, but unfortunately it counted because he narrowed the angle and made the save.”
The penalty miss was one of three gilt-edged chances to fell Gray’s way as Burnley dominated the game, but could not seal a fifth win in six league games.
The 18-goal hitman fired over in the opening minutes following great play by Scott Arfield and George Boyd, then was ruled to have turned a magnificent second half cross from Matt Lowton wide under pressure from Paul McShane.
Dyche added: “Andre’s movement for the first chance is terrific and if he puts it anywhere else, it’s a goal.
“The second one, I think (Paul) McShane actually gets a touch before him and he gets a lucky one as it just spins past the post.
“Overall, we created three or four really good chances and kept them down to very little in the way of clear chances.
“They have only lost three at home, so they are obviously no mugs. The surface didn’t help and that’s as bad as we’ve seen, for both sides, I must make it clear, which made it tough for both teams.
“But there was a lot to like about our performance today, again superbly supported by our fans travelling in numbers and if we’d come away with the win I think everyone would have said that was about right.
“We didn’t, but there were so many positives to our play today and we go away with another good point and a clean sheet on the road.”
