Swansea City boss Garry Monk was furious with Wayne Routledge's dismissal after their 1-1 draw with QPR.
Karl Henry's challenge in the 86th minute went unpunished but Routledge was sent off by referee Anthony Taylor for his reaction to the Rangers midfielder.
Swans substitute Wilfried Bony went on to score an injury-time equaliser, cancelling out Leroy Fer's first-half strike, but Monk was still seething at Henry's challenge after the match.
"It's a leg breaker," Monk said.
"I think everyone knew in the stadium apart from the official and then the double whammy of our player getting sent off for apparently kicking out.
"He doesn't kick out at all. I just hope justice is done not just for us but for football in itself.
"I'm losing a bit of faith. It's hard for us to keep faith when we continually have decisions like this, big moments within games.
"That sounds like me moaning, I'm not at all. I'm just telling you the facts.
"I hope the red card gets rescinded because that will 100 per cent be the right thing to happen.
"We'll be appealing for sure. My player goes from nearly having his leg broken to getting sent off, I don't see how that can happen."
