Newcastle United lost their fourth game on the bounce as Charlton defeated Toon 3-1 at The Valley yesterday.
Addicks striker Darren Bent scored his 20th goal of the season before former Charlton midfielder Scott Parker's 30-yard effort levelled matters.
The hosts were presented with the lead again when Craig Moore's clearance flew into the net off an unlucky Lee Bowyer.
And the points were wrapped up with substitute Jay Bothroyd's late header.
The defeat was perhaps harsh on a Newcastle side that suffered FA Cup quarter-final heartache in midweek when they crashed out of the competition at Chelsea.
For all their possession in the second-half, they failed to get back on level terms to provide their flagging season with a much-needed lift.
Charlton boss Alan Curbishley said of Bowyer's own goal which made it 2-1: "It was important to get back into the game straight away.
"I thought it was the turning point of the game, although it was on a knife edge in the second half.
"I didn't know if we'd get our third or they would equalise, but we had to wait until the 89th minute to wrap it up."
Newcastle caretaker boss Glenn Roeder also said: "All three goals were really poorly defended and should not happen at this level.
"It's a body blow when you concede weak goals like we have and our problem has been our inconsistency.
"We have to set our standards much higher and for us to lose 3-1 isn't encouraging at all and for Newcastle it isn't good enough."
