Daniel Farke expects Grant Hanley and Christoph Zimmermann to make their returns to action after the next international break.
Hanley last played for the Canaries in the defeat to Chelsea back on August 24 and has since undergone surgery on a groin injury, whereas Zimmermann injured ankle ligaments in the defeat at West Ham United a week later.
However, the central defensive pair will deliver a selection boost in two weeks time, with the City boss having to cope with just one fit centre-back in Ben Godfrey over recent months.
In other news, Mario Vrancic has recovered from his recent calf issues and could make a return to the squad for the visit of Watford.
Meanwhile, Todd Cantwell and Ibrahim Amadou have recovered from respective knocks and Tom Trybull and Onel Hernandez are back to full fitness after featuring in the Brighton defeat.
