Newcastle keeper Forster set for January loan
Clark told the Evening Chronicle: "Fraser has been fantastic in the last few games and has progressed a lot in the last 18 months.
"We have two great keepers now and the future looks good as well.
"Tim will be back in January and who knows?
"We might switch things round a bit and Fraser may go out on loan and Tim will play reserves.
"Going on loan would help him improve all parts of his game.
"And it is important for us to have the competition in the side for keepers.
"At the moment at first team level we have two top keepers battling it out for number 1 spot."
