Charlton took a massive stride towards booking a League One play-off spot on Tuesday without even kicking a ball.
The Addicks' rivals Scunthorpe beat Plymouth 2-0 at Glanford Park to make sure of their place in the post-season promotion lottery and severely dent their opponents' hopes.
Just two points and a single place separated the two teams going into the clash, but goals from Hakeeb Adelakun and Ivan Toney proved the difference in a game the hosts dominated.
Argyle's fight to prolong their season will go to the final day, but they must win at Gillingham, hope Charlton lose at Rochdale and also overturn a six-goal deficit to climb above Lee Bowyer's men.
AFC Wimbledon earned the point they needed to ensure survival as they drew 0-0 at Doncaster.
Walsall also retained their status for next season after securing the point they needed in a 1-1 draw at Bradford.
