Adam le Fondre has cancelled out Graham Dorrans's early strike as Bolton Wanderers and Norwich City remain level at half time.
After a quiet opening, Norwich took the lead in the ninth minute when Dorrans's free-kick deflected wickedly off the wall and trickled into the bottom corner past Adam Bogdan.
The Canaries almost doubled their lead a few minutes later but Bogdan managed to tip Johnny Howson's fierce shot from long range around the post, before Sebastien Bassong headed over from a corner when he was well placed.
However, The Trotters equalised against the run of play when Le Fondre neatly converted Tom Walker's low cross.
The hosts then wasted two great chances, as Le Fondre screwed an effort wide and Liam Feeney blasted wide at the far post.
Norwich almost regained the lead one minute later, but Bogdan produced another fine save to keep out Cameron Jerome's low shot.
Jerome forced Bogdan into another decent save as the visitors continued to push forward, but they couldn't find a second in an open first half.
