Darren Moore is again expected to provide a full injury update in his pre-match press conference on Friday afternoon.
Dominic Iorfa made his long-awaited return to action on Wednesday when he featured for an Owls under-23 side, but Saturday could come too soon for him.
The Addicks will be without forward pair Chuks Aneke and Conor Washington, but Jayden Stockley and attacking midfielder Scott Fraser could play some part in the match upon their return from injury.
“I think Johnnie [Jackson] and Jason Euell have done a magnificent job to steady things there,” said Moore.
“They have got a wonderful group of players. Collectively they move the ball really well. They like to play.
“They manage the ball well and commit bodies forward. They are a really exciting team to watch.

“I think both of them have brought a wonderful style of play to Charlton. They have settled the squad down and given them a real belief.
“Yes, results in recent weeks have not quite gone their way but they have not been far away. They have had one or two injuries like we have had but they are getting on with it.
But we are at home and have to continue our form and momentum. We have got to try and look to get better. We don’t want to stand still on any performance. We want to keep our performances moving in the right direction.”
