Danny Fox of Coventry challenges Danny Butterfield at the Ricoh Arena
Charlton's Championship status was left hanging by a thread after they could only secure a dogged goalless draw against Coventry at the Ricoh Arena.
Decent results for drop rivals Norwich and Nottingham Forest mean the Addicks are 12 points off safety with four games left and a dire goal difference.
But it was a brave display, with Jonjo Shelvey seeing a 'goal' disallowed and Nick Bailey firing against the post.
Coventry's best chance fell to Ashley Cain, but he shot wide late on.
Coventry City boss Chris Coleman:
"We have been in an FA Cup quarter-final and if we finish in the top half that will be a good season after what happened last year when it went to the last day of the season.
"Charlton have chased the dream and tried to come back and look what has happened to them. The likes of Coventry City have to look at that and say it is an example.
"With Norwich and Southampton down near the bottom, there are some big clubs in trouble."
Charlton Athletic manager Phil Parkinson:
"It is not looking good. We are not mathematically down but it does
not take a genius to realise that it is a tall order.
"The attitude and the application of the players was excellent today and the football we played in the first half was good, but that final ball let us down and in football that is the most important thing.
"I felt fairly comfortable defensively for most of the game and we did create a threat going forward, but that lack of quality was key."
