Charlton Athletic moved to within a point of the Play-Off positions with a 1-0 victory at home over Oldham Athletic. The win was secured by Stephy Mavididi who signed in midweek - the goal was his first strike in senior football.
Oxford United remain three points behind the Addicks. They hosted Blackpool at the Kassam Stadium and also won by a goal to nil.
Plymouth Argyle shot up the table and into 12th position with their home victory over the struggling Bury. The 3-0 triumph made it seven EFL fixtures unbeaten for the Pilgrims.
