English-born Ghana forward Tariqe Fosu scored his fifth goal in three matches to guide promotion-chasing Charlton to a deserved 1-0 Sky Bet League One victory over Doncaster at The Valley.
The winger scored the only goal of the game after nine minutes when his strike from the corner of the penalty area caught out Doncaster keeper Ian Lawlor at his near post.
Meanwhile, Joe Dodoo warmed the bench for the entire period of the game for the Addicks.
The victory takes Charlton Athletic to 5th position on the standings with 23 points after 12 round of matches.
