Hanson and Morais have both been sidelined recently with minor injuries but the pair could return against Coventry at the Northern Commercials Stadium after a positive period of recover work with club physios.
Speaking about Hanson and Morais McCall said: "We hope that they will be available for Saturday.
"They have been doing some work today (Thursday) and we'll see how they react to that. All being well though, they will be up for selection for Saturday's match.
"Thankfully, we've had no additional injuries as well from Tuesday's tough encounter at Milton Keynes Dons."
After spending the last week or so running outdoors, Stephen Darby and Rory McArdle stepped up their rehab by joining in with ball work during training for the first time.
Nathan Clarke is making progress from his calf problem, while Matthew Kilgallon is stepping up his fitness work after shaking off a slight hamstring strain.
McCall added: "Darby and McArdle took part in the football side of things this morning.
"They have been doing a fair bit of work with the physios and Robert (Lossau, Fitness & Conditioning Coach) recently but today was the first time they have been involved in football drills.
"They haven't gone into full contact with the other players just yet but it was good to get them doing some of the passing and keep-ball sessions.
"That is clearly a big boost for them and for us.
"You can do as much running as you want, as a footballer, you want to play football. They are footballers and they want to get the footballs out so that is a good lift for those two.
"Nathan won't be back for Saturday but it was nice to see him running outside.
"Matt Kilgallon is now over the little injury he had as a result of pushing himself a bit too hard, too quickly.
"He is now building his fitness levels up. It is looking a bit more encouraging around the squad, we are managing to get a few more players out of the treatment room and out onto the grass."
