LATICS saw their scoreless sequence away from the DW extend to eight matches with a stalemate at Charlton.
The visitors were up against it from the start, with goalkeeper Scott Carson injuring his knee in the warm-up.
That meant a league debut for Lee Nicholls, who put in a steady shift and was up to every challenge Charlton threw at him.
And Latics nearly had a second injury to contend with, after Nick Powell stooped low to head the ball and almost had his head removed from his neck by a Charlton defender.
Incredibly, referee Mr Martin waved play on - with Owen Coyle incensed on the sidelines.
Thankfully, Powell was able to continue, but Latics were complaining again when the official missed a clear push on Leon Barnett and instead awarded the Addicks a throw-in close to the corner flag.
Latics showed themselves for the first time when James McClean played the ball inside to Chris McCann, who had a clear shooting chance.
The home side were forced into a change moments later when Marvin Sordell for Yann Kermorgant.
And they nearly went into the interval a goal to the good when Pritchard’s corner was headed goalwards by Richard Wood, only for Nicholls to claw the ball away to safety.
Charlton picked up where they’d left off, and Dale Stephens came within a whisker of opening the scoring within seconds of the restart.
Latics came close again when McArthur fired over from the penalty spot with his left foot, before Watson missed the target from the edge of the area with a great chance.
McClean saw a shot deflect into the side-netting, with Powell volleying over from the subsequent corner when it seemed easier to score.
His blushes were spared by the offside flag being up in any case, but Latics were at least asking questions.
Powell led a dangerous Latics break as the 90-minute mark approached but, after running fully 70 metres with the ball, Espinoza took over and tried his luck only to slice his effort well wide.
And Latics were denied again in stoppage-time when McManaman’s shot was blocked by Michael Morrison.
