League One leaders Charlton ended Huddersfield's record 43-game unbeaten run with a 2-0 win at The Valley on Monday.
Two first-half goals from Charlton were enough to silence the Terriers with Yann Kermorgant (23) and Hogan Ephraim (43) finding the net.
The Addicks came very close to increasing their lead twice in an open second half when Kermorgant's header and a shot from Danny Ward both struck the crossbar.
Huddersfield had chances of their own but Ben Hamer was equal to Jon Parkin's well-struck shot to push it onto the post.
Though the Terriers worked tirelessly to keep their record and improved in the second half it was not enough to phase Charlton and the win put Chris Powell's side seven points clear at the top of the table.
"We played a very good side, who made us work very hard, but this was just another win," said Powell.
"For us to be the ones who have stopped the record is pleasing for us as a club. Maybe people will remember us now as the team that stopped Huddersfield."
Meanwhile, Lee Clark said a defensive mistake and a poor refereeing decision were the downfall of his side; "For the first one [goal] we're marking the wrong side, for the second the referee is pointing for our throw, and then he all of a sudden lets the linesman over-rule him and they take a quick throw."
Clark was not shy to express his anger about the officials; "I don't want to be ringing referee's bosses up and asking about the quality and standard of them, but obviously I need to have that conversation again and ask him to have a look at one or two incidents.
"This was a referee who gave a controversial decision against us two years ago here, so it's not something I'm surprised about."
The loss leaves Huddersfield in 3rd place – eight points behind Charlton.
