Charlton continued their excellent start to the season with a narrow victory at London rivals Brentford.
The Bees dominated the opening period with Niall McGinn hitting the post with Addicks keeper Ben Hamer well beaten and Clayton Donaldson heading wide.
Bradley Wright-Phillips bundled home from close in after Danny Green's low centre to give the visitors the lead after the break.
Hamer saved well in injury-time to deny Mike Grella an equaliser.
The game ended with 10 minutes of stoppage time after home defender Shaleum Logan had to be stretchered off the pitch after colliding with his own goalkeeper Richard Lee.
The victory consolidates Charlton's position at the top of League One, where they lead second-placed Huddersfield Town, who they face at the Valley next week, by five points.
Brentford remain in ninth place, two points outside the play-off positions.
Wright-Phillips' goal was his 14th of the campaign and Charlton's 2,000th away from home in the Football League.
VIEWS FROM THE DRESSING ROOM
Brenford boss Uwe Rosler told BBC London 94.9:
"The players are gutted about Shaleum Logan. All our thoughts are with him. He's getting a scan at the hospital.
"We didn't deserve to lose. I thought we were the better team for 90 minutes apart from a spell just before and after the incident when they punished us.
"I thought we were the better side. but they have a lot of experiece and know how to cancel out games.
"And they have that bit of extra quality up front with a player who cost them £1m"
Charlton boss Chris Powell told BBC London 94.9:
"It was a hard fought away win but you've got to win at places like this and win ugly sometimes.
"They definitely had the better of the first half.
"The players dug in and I'm very proud of them because seasons are built on tough away results when you are not playing well and you still pick up three points."
