Joe Newell reckons Ianis Hagi's high challenge would have been a free kick anywhere else on the pitch as Hibs were denied a penalty at Ibrox.
The Easter Road club left Ibrox with nothing despite a second half revival from the away side as Rangers ran out 1-0 winners.
Jack Ross' men had a big shout for a penalty as Hagi challenged Newell with a high boot.
But Willie Collum waved away appeals as Rangers would go on to seal the victory.
Newell admits he doesn't know if there was contact from the Romanian winger, but the Hibs midfielder believes it would have been a foul if it wasn't in the box.
He said: “I think it is one of those, if it is on the half-way line it is a foul all day long.
“I have gone in to head it and I think he has booted the other side of the ball so I don’t know if there is actual contact but if there is a high boot, it is dangerous play, and it is a free-kick anywhere else on the pitch. But, because it is a penalty I think the ref is a wee bit more nervous to give it.
“He said I had ducked down but I don’t know. Referees have a tough job but if it is on the halfway line, he probably gives it.
“There was a shout from a corner as well [when Jamies Tavernier dunted Ryan Porteous] but to get results here you need to play well, get a wee bit of luck and decisions have to go your way and we didn’t get them.
”I don’t see too many of Rangers’ games here at Ibrox but I can’t imagine that there are too many where they are protecting the ball in the corner and wasting time in the last five minutes,” said Newell. “That is not a dig but I think it shows some respect to us and how we played in the second-half.”
