Ince missed Sunday's 2-0 defeat at Watford due to a foot injury and Forster-Caskey came off during the first half with a hamstring problem.
"Ince picked up a foot injury which meant that he couldn't train for the last couple of days," said assistant boss Nathan Jones.
"He's had a lot of football lately and that's why we pulled him out. Hopefully we will have him back in training this week.
"Jake pulled up with a little hamstring problem and that won't be serious either. Hopefully he'll be back soon as well, and it'll be all hands to the pump again and we won't be stretched."
