Walsall boss Dean Smith has an unchanged squad at his disposal.
Playmaker Emmanuel Ledesma serves the final game of his three-match suspension, meaning he will return for the trip to Southampton on the last day.
Centre-back Clayton McDonald will miss the remainder of the campaign having dislocated his shoulder, while full-back Aaron Lescott remains sidelined with his knee ligament strain.
The Saddlers go into their penultimate match of the campaign just one point above the drop zone, knowing victory would have a massive impact on their survival hopes ahead of their final day trip to St Mary's.
Defender Oliver Lancashire told the club's official website: "We have to be positive. We go into the game determined to get the three points on offer.
"We would have taken this position three months ago. It's in our hands and we have to make sure we can finish the job off."
Kyel Reid and Scott Wagstaff return to the Charlton squad.
Reid is available after missing Monday's win over Rochdale through suspension and fellow winger Wagstaff has recovered from a hamstring injury.
Midfielder Jose Semedo is still banned after his dismissal against Bristol Rovers on Saturday, while skipper Christian Dailly's season came to a premature end three weeks ago courtesy of a five-match suspension for his third red card of the campaign.
Goalkeeper Rob Elliot is fit after a knee injury but Millwall loanee John Sullivan looks to have done enough to keep his place.
Winger Johnnie Jackson is back in training after an Achilles injury but is unlikely to be risked while full-back Kelly Youga (knee) and striker Joe Anyinsah (ankle) are still out.
