Celtic striker Marc-Antoine Fortune has expressed his disappointment at being denied an Old Firm debut goal against Rangers.
The former Nancy striker thought he had headed the Bhoys into a priceless early lead against Gers only for the goal to be chalked off.
The Celtic striker looked to have fairly won an aerial challenge with Rangers keeper Allan McGregor to head the home side into a 19th-minute lead.
However, referee Steve Conroy disallowed the goal for a foul, much to the French striker's disappointment.
Scott McDonald did open the scoring late on, but Gers secured a share of the spoils thanks to Lee McCulloch swift response.
"I jumped and never touched the keeper, only the ball," he told the club's official website.
"My first impression was that I had scored because the referee ran to the centre and then I saw him run back towards the goals, so I didn't understand.
"At first I thought the goal was offside, but then the referee told me it was for a foul. Sometimes the referee makes mistakes but that's just football.
"For about five seconds I was really upset, but then I just kept on playing.
"I think everyone that plays for Celtic and Rangers wants to score in the derby, particularly if you are a striker.
"This is my first year here so people will think I should score. I did - but then the referee made his decision.
"But I think the fans saw that I gave my best for them and there are a lot of games left so I will do my best to score in them."
