A poor game between two poor teams ended with Millwall once again taking the spoils.
The game was a subdued affair with the goal coming from a mistake.
Bradley Pritchard gave possession away in the Lions half. Martyn Waghorn put Scott McDonald through and the striker's long range shot deflected off Dorian Dervite to wrong foot Ben Hamer.
Substitute Marvin Sordell created Charlton's best chance but Simon Church shot straight at David Forde.
