Charlton are short of options up front when they host Northampton.
The Addicks remain without the suspended Lee Novak, who was sent off in the opening-day win against Bristol Rovers.
Tony Watt this week left for Belgian side Oud-Heverlee Leuven and Josh Magennis is yet to appear this season.
Recent signing Ben Reeves also remains short of match fitness, while Mark Marshall is a long-term absentee.
Northampton will have defender Leon Barnett available again following a one-match suspension.
