Loan striker Shefki Kuqi is out of next Saturday's trip to Scunthorpe with the hamstring strain he suffered during the weekend 2-0 victory over Charlton. Midfielder David Norris limped off with a heel injury during the first half of that game and is also a doubt for the trip to North Lincolnshire.
Physio Matt Byard told the club site: "Shefki's problem is a hamstring strain and he will definitely miss the Scunthorpe game at the weekend.
"We will monitor his progress through the week and have more of an idea on when he may be back either at the end of this week or the start of next week, depending on how his rehabilitation goes.
"We have not ruled David out of Saturday's game completely yet, although he is obviously doubtful.
"He has a plantar fascia strain which is quite a common injury. He is keeping the weight off it at the moment and he will be resting up this week and we will see where that leaves us in a few days time."
