Ben Amos is set for scan this week after suffered damage to his hand in training on Friday.
Jordan Archer retained his starting place between the posts for Sunday’s 2-1 FA Cup win over Hull City.
Asked why he did not rotate his keeper for the competition, Harris replied: “Ben has got a chipped bone in his finger on Friday in training. He’s not been able to see a specialist yet.
“We won’t know the extent of the damage until probably tomorrow.”
Shaun Hutchinson could resume training this week. He has missed the last two matches with a deep cut to his shin – broken glass in a rubbish bag causing the issue as he put it in the bin.
Harris said: “He’s walking around and fine but we won’t know more until he tries to put a shinpad on and gets out on the training pitch.”
Conor McLauglin is ruled out with a quad injury.
Fred Onyedinma is back from his loan spell with Wycombe.
“He has been looking unplayable the last couple of days in training,” said Harris.
