Fulham captain Tom Cairney was left "bamboozled" by the refereeing for their 1-0 defeat at Chelsea.
Chelsea defender Malo Gusto escaped a red card in the first-half, which left the Cottagers frustrated.
Cairney said: "When you think Dominic Calvert-Lewin got sent off for not touching anyone (for Everton at Crystal Palace in the FA Cup, a decision that was overturned on appeal) and then that one was just a yellow card... I am just bamboozled.
"He has hit him clean. He has got shin pads but he has hit him high and in modern football you can't do that.
"We saw it on the laptop at half-time and all six studs are on his leg.
"We asked the ref at the time and he said it had gone to VAR to be checked, so we are so confused. I am just really confused, that's normally a straight red.
"Maybe you don't get these things away from home. It is strange."
