The 33-year-old, sidelined with a foot injury sustained in early December while on loan for Rotherham, has this week been given the go-ahead to return to full training.
Bradford manager Phil Parkinson told the club's official website: "Guy saw his specialist this Tuesday and he's happy with the progress he's been making.
"Guy's now back training with the rest of the squad as a result. He's been told that he may still get some pain from it, but it's something he'll probably have to just get on with."
