The midfielder picked up a thigh strain in training on Saturday, ruling him out of Sunday's win against Everton.
Vlad Chiriches, Erik Lamela and Sandro remain sidelined.
"Gylfi’s not too far away, he has a slight strain," reported Head Coach Tim Sherwood after training on Tuesday.
"Vlad still isn’t right. He has a back injury and it might be some time before he returns.
"Erik had a thigh strain, he’s over compensated with that and now it’s referred to his back.
"That’s not great news, but Younes is back in training, Jan has played a few games now and he looked stronger at the weekend, Paulinho is back, Andros as well, he just needs minutes and we all know what he can do once he’s firing again."
