Howe recently provided an update on Wissa's progress, stating that the 29-year-old had a check-up with a specialist and is expected to be out for around eight weeks instead of the initial six-week timeline.
This means Wissa will not return to the pitch until after the October international break, which is a setback for the team. Despite this, fellow summer signing Nick Woltemade has stepped up and scored three goals in six appearances, taking on a key role in the team.
Woltemade is likely to start against Nottingham Forest this week as Newcastle aims to climb into the top half of the table.
