Glasgow giants Rangers and Celtic will have to replay their Scottish Cup fifth round clash after a 2-2 draw at Ibrox yesterday ended with both sides reduced to 10 men.

Jamie Ness opened the scoring for the hosts in the third minute with his first Rangers goal before Kris Commons, playing his first Old Firm game, drew Celtic level in the 15th minute.

Steven Whittaker restored Rangers’ lead after Celtic goalkeeper Fraser Forster was sent off for bringing down Steven Naismith in the box.

But Celtic captain Scott Brown made it 2-2 in the 64th minute before, in another twist, Naismith – already booked for a first half foul on Mark Wilson – was sent-off for diving inside the visitors’ penalty area.

The sides will now meet in a replay at Parkhead on March 2.

At Ibrox, Rangers made three changes as Nikica Jelavic and El-Hadji Diouf were handed Old Firm debuts while Daniel Majstorovic recovered from injury to play in the centre of Celtic’s defence.

Forster saw red in the 38th minute after bringing down Naismith in the box. Zaluska replaced Commons and his first task was to pick the ball out the net after Whittaker sent the Polish keeper the wrong way to bury the penalty in the bottom right-hand corner.

The home side failed to make their advantage count and Brown hauled the Hoops level in the 65th minute. The Celtic captain was given time and space 20 yards out and he curled an angled shot into the far corner past the outstretched arm of McGregor.

Substitute Georgios Samaras saw a header cleared off the line before Rangers were reduced to ten men in the 76th minute when Naismith received a second yellow after referee Callum Murray adjudged he had dived in the box although there appeared to be slight contact from Charlie Mulgrew.

Joe Ledley and sub Kyle Lafferty both came close to sealing a later winner for their sides, who will now meet an incredible seven times this season.
