The 19-year-old has been linked with a loan move to Hull City.
Joyce has also revealed that youngster Ryan Tunnicliffe could get a first-team chance next season.
“There’s bound to be interest from the Championship as they both did well last year,” Joyce told the Hull Daily Mail.
“The reserves won everything and Keane won the (reserves’) player of the year.
“For sure he will go out on loan but Tunnicliffe may well be around the first team.”
