Charlton boss Chris Powell was delighted as the Addicks 2-0 home win ended Huddersfield’s unbeaten league of 44 matches on Monday night.
"For us to be the ones who stopped their record is pleasing and everyone will remember us as the ones who did it. But there are plenty of games still to go. We have done nothing yet," said Powell.
"It was a good advert for League One. They settled quicker than us but as the game went on we grew in confidence. It was a big occasion. I tried to play it down with the squad but it was a big game for a lot of them and they came through well. But we've done nothing yet."
Huddersfield counterpart Lee Clark admitted the defeat in paled into insignificance in the wake of the death of close friend Gary Speed.
"This is a big boys' game and sometimes you get a knock-back but I've had the biggest knock-back ever," Clark said. "Don't think this defeat doesn't hurt but what happened Sunday morning has put everything in perspective. It was a hammer blow when we got the news travelling down to London.
"I only had a short time in terms of being a colleague of Gary's but we hit it off straight away and became very close. He was a fantastic player but if you times that by a million, you'll find out what the man was like as well."
On the defeat to Charlton, Clark added: "We went out of with a bit of a whimper. At half time we were two down and we hadn't put Charlton under any pressure. I'm disappointed, but don't take any credit away from Charlton. They are having a fantastic season."
