Charlton boss Lee Bowyer hopes to have striker Igor Vetokele back for the play-offs.
The Angolan forward has been in resurgent form recently, scoring twice in his last three appearances as he struck up a useful partnership with Lyle Taylor.
But he was unable to feature during the South Londoners’ 4-0 win over Rochdale on the final day of the regular season.
The Addicks will face Doncaster Rovers in the semi-finals, with the first leg at the Keepmoat Stadium next Sunday.
Bowyer said that he is hopeful of Vetokele returning in time.
“We were doing a bit of finishing on Thursday and his thigh just tightened up a little bit,” he explained.
“We just couldn’t take the risk [against Rochdale]”
