Town manager Joe Royle says he expects skipper Jim Magilton to be fit for Sunday's crucial East Anglian derby at Carrow Road but is less confident about central defender John McGreal.
Magilton was substituted towards the end of last night's game at Stoke having picked up a dead leg, following McGreal on to the bench who had been substituted earlier with a knee ligament problem.
Royle told the club site: "We will know more about John's injury later today but it's knee ligaments and at this moment he has to be doubtful for the weekend.
"Jim has got a dead leg but we are much more hopeful with him, and I'm confident he will be fine for Sunday.
"The lads had a light session this morning and will have a rest day on Thursday before we start to work towards the Norwich match.
"It was a game we should never have lost at Stoke but we have not lost too much ground because other teams around us dropped points.
"That's the nature of this division but Sunday is obviously a big game for us for many reasons."
