After winning just one of their previous 10 games, Morecambe will have to improve in their final 10 fixtures if they are to avoid relegation.
The Shrimps made the trip to Montgomery Waters Meadow on Saturday to face Shrewsbury Town, who took a two-goal lead before Dan Crowleyhalved the deficit in first-half stoppage time.
However, an 84th-minute effort from Chey Dunkleyensured that Morecambe headed back to the North West empty-handed, with the 3-1 defeat extending their winless run to four matches.
As a result of Saturday’s loss, Morecambe remain in the bottom four, with two points separating them from Accrington Stanley, who sit just outside the drop zone and have played two games less than the Shrimps.
Although Morecambe are winless in 13 away league games, they have proven to be a tough team to beat on home turf, losing just one of their last 12 home matches in the third tier.
With 11 points separating them from the drop zone, 16th-placed Charlton are comfortably clear of the bottom four, but they will be desperate to end their poor run of form.
In Saturday’s home meeting with Accrington, the Addicks had to be content with a 1-1 draw after Steven Sessegnon cancelled out Shaun Whalley’s opening goal before half time
Sessegnon’s strike may have ended a run of four games without a goal, but the result extended Charlton’s winless run to five matches.
Sitting three points adrift of 12th position, Charlton still have the chance to record a top-half finish, which would represent an improvement on last season when they ended up in 13th place.
Having failed to win their previous two meetings with Morecambe, Charlton will be hoping that it is third time lucky as they attempt to claim their first league win over Tuesday’s opponents.
