Charlton extended their lead at the top of League One by beating London rivals Brentford at The Valley in a game delayed by a power cut.
Michael Morrison scored the hosts' opener midway through the first half when he headed in Danny Hollands' cross from close range.
Danny Green made sure of the Addicks win by sidefooting home from inside the box late on.
Johnnie Jackson also went close for Charlton but his shot hit a post.
Leon Legge and Niall McGinn both went close for Brentford, who have lost both of their League One meetings with the Addicks this season, with first-half volleys.
Marcus Bean had the visitors' best chance after the break when he shot wide from 10 yards out.
With promotion rivals Sheffield United losing 3-2 at Carlisle, it means the Addicks have now extended their lead at the top of League One to five points.
VIEWS FROM THE DRESSING ROOM
Charlton boss Chris Powell told BBC London 94.9:
"They have been very good away from home and we knew it would be a tough game, especially after their comeback against MK Dons, but it was up to us to handle that.
"I'm really pleased with today and I think all our fans are happy with a 2-0 win and a clean sheet which we haven't had for a while.
"They wanted to respond after [losing to Leyton] Orient, we all felt hard done by with what happened there, so today it was about getting the points."
Brentford boss Uwe Rosler told BBC London 94.9:
"Overall it's unfortunate that we couldn't bring our good play into something that counts.
"It was a clear penalty and that cost us the game. That would have been the equaliser and that would have been a fair result."
