McGregor said: "It was probably a foul against me, if anything.
"You get your body in — you've got to try and stop them from scoring.
"It's not a foul.
"He kicks me, if anything.
"So, nah, no chance."
However, interim Rangers head coach Barry Ferguson disagreed.
He believed his team should have been given a chance to score from 12 yards.
Ferguson said: "If that's in the middle of the pitch, it's a foul.
"But it was in the box, and it wasn't given as a foul.
"I just need to move on quickly because I don't want to start saying things that are going to get me in trouble."
Rangers had to settle for a point, denying them three consecutive victories against Celtic.
Adam Idah's second-half equaliser proved crucial for the Parkhead side as they avoided defeat.
Celtic will face Hibernian next weekend in their penultimate home game of the season.
