Mateus Mane canceled out Keane's opener for Everton. Keane, for violent conduct, and Jack Grealish were sent off late on.
"It was not violent, it is not forceful, and it is not deliberate,” said Moyes.
“All those things I have said, it should not be a red card. Today, this was in the game on a ball coming up. If everybody grew their hair longer, there could be a chance you are going to get your hair pulled. I thought it was a ridiculous decision.
"It can't be violent conduct for that. In an action in the game, how would that warrant a red card? People getting pulled back in the box every five minutes, but you are letting them go? Ridiculous."
Moyes continued: “I think everybody was frustrated. I think when everyone saw the screen, they couldn’t believe it. I have had many times to see it now. It is certainly not deliberate.”
