Joe Colbeck, Craig Bentham, Tom Penford and Luke Medley have all been made available for loan.

"We're going to have to trim the squad because we've got a lot of players not getting enough football," McCall told the Telegraph and Argus.

"Most of them have played a lot for the reserves over the years and you can only do that so long."

McCall added: "For the sake of them as much as us they need to go out and play first-team football."

Midfielder Colbeck, 20, has made 50 league appearances for the Bantams, while Bentham and Penford have also played a number of first-team games.

Striker Medley, 18, has scored once in two substitute appearances for Bradford this season.
