Chris Eagles completed his move to Charlton on Thursday morning and goes straight into the squad that will travel to Wigan.
Guy Luzon believes in taking just the 18 players he intends to use in a match, so Eagles is assured of at least a spot on the bench at the DW Stadium on Friday evening.
Eagles can be a match winner on his day and he could prove to be an exciting signing for the Addicks.
It is likely that the Hemel Hempstead born wide man will wear the number 9 shirt, which has been vacant all season.
