Charlton lead 1-0 at Rotherham after a Johan Berg Gudmundsson strike on the half-hour mark.
Charlton Athletic's unbeaten Championship record this season looks set to continue after Johan Berg Gudmundsson put them 1-0 up against Rotherham United.
The hosts started the brighter at the New York Stadium, with Alex Revell making room for himself in the box to strike at goal only to see his effort easily gathered by Stephen Henderson.
Charlton gradually came into the game and almost took the lead when Johnnie Jackson powered a strike from distance just over Scott Loach's crossbar.
Despite the early pressure from the hosts, it was the Addicks who managed to find the breakthrough.
Iceland's Johan Berg Gudmundsson cut inside from the right and fired a superb shot from distance, beating Loach at his far post.
