With Neil Sullivan suspended, Walker is preparing for Premiership football again this weekend while Kelly is on loan at Kingstonian.
Boss Chris revealed: "Hans Segers will be in goal. We have a bit of problem in that Gavin Kelly, who has done ever so well for me, is on loan at Kingstonian.
"They are still in the FA Cup and what was a one-month loan will now go into a third month.
"It’s trying to get the balance right. He’s done well but of course he needs competitive games and we wouldn’t want to take that away from him.
"But with Hans, although he’s the goalkeeping coach, it doesn’t take away from the quality he has on the football pitch. I look as it as a bonus for us."
Ben Thatcher, on his way back from a groin injury, will also take his place alongside the youngsters who have been knocking on the first team door all season.
Chris said: "Ben will be involved, his first competitive game for a while, John Jackson is involved after linking up with England Under-18s and then there’s the likes of Etherington, Hillier, Thelwell, Gardner, Toner, McEwen, Davies — they have all been regulars over the last five or six games."
The latest player to feature in the Premiership was Dave McEwen, who had a 25-minute run out at Everton on Saturday.
Chris added: "It was nice for him. That’s what he works hard for, to be given the opportunity.
"He’ll probably say he only got that opportunity because of the injuries we’ve had but that’s part and parcel of it. You have to take those chances when they come."
