Charlton 2-2 Scunthorpe
Bobby Grant equalised in injury-time as Scunthorpe came from two goals down to draw with Charlton.
Johnnie Jackson's looping header gave the Addicks the lead before Bradley Wright-Phillips nodded home a Danny Hollands cross.
Grant, who went close with an overhead kick, did pull a goal back when he fired past Rob Elliot.
And the Iron striker converted from close range to grab a point and end Charlton's 100% record.
VIEWS FROM THE DRESSING ROOM
Charlton manager Chris Powell told BBC London 94.9:
"It's one more point than we had this morning and I'm sure everyone is feeling despondent but we're still unbeaten.
"Of course from the position we were in at 2-0 up, you want to see out the game and get the three points but I have to say their keeper made three fantastic saves.
"The first goal we conceded was really unlucky and it's a lesson learnt for some of our younger players."
Scunthorpe manager Alan Knill told BBC Radio Humberside:
"I thought we deserved something (from the game), it would've been a travesty if we hadn't.
"They had chances but I thought we had a fair share of chances as well.
"Just at the moment we're having a problem keeping it out of our net and we have to always come back from behind."
