Rangers and Celtic will have to do it all again after their action-packed Scottish Cup tie - which saw both sides reduced to 10 men - ended in a 2-2 draw at Ibrox.
Jamie Ness grabbed his first goal for Rangers before his early opener was cancelled out by Kris Commons. Steven Whittaker then converted from the penalty spot after Celtic goalkeeper Fraser Forster saw red for a challenge on Steven Naismith.
But Scott Brown hauled the Hoops level again and Naismith picked up a second booking as both teams failed to find the winner to progress to the quarter-finals. The replay at Celtic Park means the Old Firm rivals will now meet seven times this season.
