Sheffield United boss Paul Heckingbottom was left disappointed with Oli McBurnie after defeat at Burnley.
McBurnie was sent off before halftime during the 5-0 thrashing.
Heckingbottom said: "We've given Burnley the advantage they need. A huge lack of discipline and we've gone down to 10 men.
"I've not seen the first, I've seen the second. If they're two yellows there's nothing we can do about it anyway.
"It's a bit different when you're already on a yellow. You have to be careful. We all know that. The game has changed. We can't appeal or look at it. You can't afford to do that."
