Charlton will hand fitness tests to Dan Seaborne and Danny Haynes ahead of the visit of Peterborough.
On-loan defender Seaborne and midfielder Haynes, who scored on his last appearance against Burnley, missed the 1-1 draw with Huddersfield at the weekend with knocks.
The pair will be assessed ahead of kick-off but manager Chris Powell will not take any risks.
The draw against Lee Clark's side ended the Addicks' three-match winning run and, with a derby match with Millwall looming at the weekend, the manager is thinking about making changes.
``The conditions on Saturday will have taken a lot out of the players' legs, so whether I freshen it up and put in some fresh players and fresh legs, we'll have to wait and see,'' Powell told the club's official website.
On-loan striker Saido Berahino is an injury concern for Peterborough.
West Brom teenager Berahino limped off early in the second half of Posh's 1-1 draw with fellow strugglers Ipswich on Saturday due to a knee problem.
He was replaced by new signing Dwight Gayle, on loan from Dagenham & Redbridge, at Portman Road and the 22-year-old would most likely make his full debut against the Addicks if Berahino is not fit.
With Nathaniel Mendez-Laing (Portsmouth), Emile Sinclair (Barnsley) and Tyrone Barnett (Ipswich) having been transfer-listed and shipped out on loan following a recent breach of club discipline and wing-back Tommy Rowe (ankle) still injured, boss Darren Ferguson's options to change things around are limited.
Craig Alcock, Gabriel Zakuani, Danny Swanson, Kane Ferdinand and Jonson Clarke-Harris are available though should he wish to make any alterations to his starting line-up.
