Chuks Aneke is set to have a scan on his injured hamstring on Tuesday.
The striker was substituted shortly after scoring the opening goal in Charlton’s 4-0 win over Reading on Saturday.
Speaking in his pre-match press conference ahead of Tuesday's game against Lincoln City, Head Coach Michael Appleton said: “We’ll know a little bit more tomorrow. I believe he is being scanned tomorrow.
“Once we get the results back from the scan we’ll have a little bit of a better idea. He seems to be in reasonable spirits considering I know he’s got a little bit of a history with his hamstring. I think it’s one where we don’t want to get too far ahead of ourselves and second guess anything until we get the results.”
