Charlton got their fifth draw of the season with a 1-1 at Rotherham today, having led 1-0 through a Gudmundsson goal on 27 minutes at half time. The Addicks have dropped out of the play off places to seventh.
Charlton took the lead when Gudmundsson cut in from the right and curled a shot low into the far corner, with a deflection off the foot of Rotherham midfielder Paul Green taking the ball wide of Loach's dive.
Rotherham's equaliser came as Becchio headed in a cross from fellow substitute Ben Pringle after 69 minutes.
Both sides had chances to snatch all three points in the closing minutes. Scott Loach saved smartly on the line from Frederic Bulot before Joe Skarz's close-range header was tipped round a post by Henderson.
Possession was 53-47 in favour of the home side and they had six shots on target to Charlton's four.
Derek from Dymchurch says, 'We can't keep sitting back when we have a lead and inviting on pressure. And we have to stop making defensive errors. We should have beaten Rotherham. We've stuttered along but, mark my words, our bad run starts next Saturday.'
