Charlton and Rotherham both scored in the final seven minutes as their Championship encounter ended in a draw.
Addicks midfielder Jordan Cousins broke the deadlock on 83 minutes, shooting home from six yards out.
The visitors went close to an equaliser with three minutes to go, but goalkeeper Marko Dmitrovic pushed away Paul Green’s close-range header.
But the Millers did grab a point when Danny Ward converted a high ball into the box in injury time.
It was enough to move Steve Evans’s side up a place into 20th in the table, while Charlton slip to 18th.
Guy Luzon, taking charge of the Addicks for the first time, almost saw his side fall behind when Ben Pringle’s shot against the post.
Charlton responded and almost took the lead with their first attempt, but Igor Vetokele diverted a Chris Solly corner over the bar.
The woodwork intervened again when a Charlton counter-attack finished with Johann Gudmundsson chipping Adam Collin, only for his shot to strike both posts.
Andre Bikey’s acrobatic effort for the home side then went narrowly over, before the deadlock was broken by Cousins.
After Dmitrovic’s excellent save from Green, Adam Hammill also went close for the away side before Ward finally equalised in injury time.
