Match ends, Huddersfield Town 2, Norwich City 2.
Norwich substitute Jamar Loza struck a dramatic late equaliser to deny Huddersfield victory after James Vaughan was sent off for celebrating what looked like a winning goal.
Loza side-footed in at the far post two minutes after Vaughan scored in the sixth minute of added-time.
Earlier, the Canaries' Wes Hoolahan replied to Ishmael Miller's opener.
Although the point was welcome, Norwich still lost ground on the Championship race for automatic promotion.
Six straight wins have propelled Alex Neil's side into contention for a top-two finish and an immediate return to the Premier League.
But after their second consecutive draw, they are now five points behind the top two of Watford and Middlesbrough, who both won.
Chris Powell's Huddersfield, who are now 10 points clear of the bottom three, deserved their point after a spirited performance but have still not beaten the men from Norfolk for 14 years.
Both sides were intent on scoring from the start, even if they were using differing methods.
Huddersfield were given a let-off in the sixth minute when Norwich midfielder Bradley Johnson was adjudged to have handled before bundling the ball home from Cameron Jerome's knockdown.
Amid Huddersfield's furious protests, referee Nigel Miller consulted assistant Lisa Rashid and the goal was ruled out.
Ten minutes after the break, Huddersfield carved out the opening goal as Jacob Butterfield clipped the ball into Miller on the edge of the area and the striker deftly turned before slamming home his second goal of the season from 12 yards out.
Huddersfield's lead did not last long though. Neil sent on substitute Hoolahan and five minutes later he steered home Gary Hooper's cross.
There was no let up to the pace as Vaughan seemed to have snatched it for Town when he converted Butterfield's cross.
But after the striker received a second yellow for his celebration, Norwich swept forward with the last action of the game and when Graham Dorrans's shot rebounded to the far post, Loza swept home an unlikely equaliser with the last meaningful kick of the game.
Norwich manager Alex Neil:
"As far as I'm concerned it was a goal for Bradley Johnson at the time. The lineswoman had run back to the halfway line.
"The referee had given the goal and the Huddersfield players came over and that seemed to put her under pressure and all of a sudden somebody has seen an infringement.
"Whether it was a foul or not, I don't know, I haven't seen it. Somebody mentioned handball so if it was, fine, but if you haven't seen it I don't think you can give the decision."
Huddersfield manager Chris Powell:
"After a nervy start the disallowed goal galvanised us and changed the whole atmosphere and we started to play.
"I should be sitting here with a win, it was a good goal by Ishmael, a comeback by them, but to score when we did - I'm sure everyone thought that was going to be the winning goal, but it wasn't to be.
"I've got to take the positives - the players' efforts. I've got to commend them, they were superb playing against a side that (last season) were in the Premier League."
