A late rally wasn't enough as Charlton lost at Derby County on Tuesday night.
Goals from Danny Green, pictured, and Yann Kermogant in the space of three minutes gave Derby a fright as the Addicks battled back from 3-0 down.
And Chris Powell's men almost avoided a third straight Championship defeat when Salim Kerkar's injury-time header was cleared off the line.
Jamie Ward's volley gave County a seventh-minute lead and Craig Bryson made it two on 53.
Ward added his second from the penalty spot 10 minutes later after a foul by Green.
Addicks midfielder Green launched the revival with a 30-yard screamer on 70 before crossing for Kermogant, who finished from close range.
Charlton visit Ipswich on Saturday.
