Charlton have played twice since their last League One match on November 27, which ended in a 1-0 defeat at Shrewsbury Town, triumphing in both the EFL Trophy and FA Cup.
Indeed, the Addicks beat Aston Villa Under-21s 2-1 in the EFL trophy at the end of November before securing their spot in the third round of the FA Cup courtesy of a 2-0 victory at Gateshead on Friday.
Charlton’s league form has been inconsistent for much of the campaign, boasting a record of six wins, five draws and nine defeats from 20 matches, which has seen them collect 23 points to sit 15th in the table.
Johnnie Jackson remains in charge of the club on a caretaker basis, and it has been a disappointing League One campaign thus far for a team that finished seventh in the third tier last term, only missing out on the playoffs on goal difference.
The London outfit are unbeaten in their last three matches against Ipswich in all competitions, although two of those encounters have finished goalless, including the corresponding game last term.
Ipswich, meanwhile, will enter this contest off the back of a goalless draw with Barrow in the FA Cup on Saturday, so the two sides will have to lock horns once again in a replay.
Paul Cook was sacked as head coach following the clash with Barrow, which meant that the club had won just two of their last nine matches in all competitions.

In a statement released on the club’s official website, Ipswich’s chief executive Mark Ashton said: “At this moment, there is no one lined up to replace Paul. There will be an extensive search to find the best replacement for the club.”
The Blues, at the time of writing, are yet to name a caretaker manager for this match, but Ashton is expected to make an announcement on Monday.
Ipswich, who finished ninth in League One last season, are currently 11th in the table, seven points off the playoffs, while they have been victorious in just one of their last four league encounters – the 2-1 home success over Crewe Alexandra on November 28.
