Shrewsbury ensured a 10th successive campaign in League One after their 1-1 draw at Charlton.

The visitors have not won in six matches, drawing four times, but sharing the spoils at The Valley was enough to secure safety.

Dan Udoh put Shrewsbury ahead in the 23rd minute with his 11th goal of the season, slotting smartly across Addicks keeper Harry Isted.

Before that Town had gone close when Morgan Feeney’s header hit the left post with the ball rebounding on to Tunmise Sobowale and once again coming back off the woodwork.

Charlton levelled almost instantly after the restart. Addicks captain George Dobson, who has signed a pre-contract agreement to join Hungarian club Fehervar, raced on to Connor Wickham’s through ball and confidently went past Shrewsbury keeper Marko Marosi to finish into an unguarded net.

Addicks midfielder Karoy Anderson headed over from close range after meeting Thierry Small’s cross from the left shortly before the hour mark while Marosi got down well to parry away substitute Daniel Kanu’s strike.

Charlton extended their unbeaten run to 14 league matches, 10 of them draws.

Thomas O’Connor’s goal secured Wrexham a 1-0 FA Cup win at Shrewsbury as they reached the fourth round for the second year running.

The hosts went close midway through the first half when Jordan Shipley floated a cross to the back post for Tunmise Sobowale to run on to but he skied his effort over the bar.

Wrexham had an effort just after half-time through Paul Mullin, who won the ball wide and cut in to the box from the left, but Marko Marosi parried away the danger.

Mal Benning made a surging run from the halfway line into the box just past the hour mark, but his effort clipped the crossbar and went out.

The Red Dragons found the breakthrough in the 72nd minute as George Evans played the ball into O’Connor’s path and the midfielder’s deflected strike found the back of the net.

Shrewsbury went close to a late equaliser as the ball fell to Taylor Perry just yards out, but his effort went inches wide.
