Charlton manager Lee Bowyer is sweating over the fitness of Marcus Maddison ahead of his side’s Sky Bet League One clash against Rochdale.
Maddison has been sent for a scan on the ankle injury he sustained in Charlton’s 2-0 defeat against Accrington on Friday night.
Ben Watson (hamstring) is likely to be unavailable, while Darren Pratley will serve the second of his three-match ban.
Andrew Shinnie (thigh) is not ready for a comeback. He remains sidelined along with longer-term absentees Ryan Inniss, Alfie Doughty and Akin Famewo.
Rochdale will be looking to retain the momentum gained from their impressive second-half comeback against Crewe.
After they were struck down by a Covid-19 outbreak, Rochdale came from three goals down to salvage a point in their first match in three weeks.
Ryan McLaughlin and Paul McShane will be pushing for a place in Brian Barry-Murphy’s line-up on Tuesday evening after they started on the bench in the weekend draw.
Elsewhere, Barry-Murphy has no fresh injury concerns ahead of his side’s midweek trip to the Valley.
