Talking to the Club website Williams commented: "Injuries are the worst thing for any footballer and you miss the banter about the dressing room as well as actually playing and training.
"I've been working through the summer with the physio team and fitness coach Simon Thadani to get back, and joining in with the lads at pre-season was always my target."
Gavin missed training yesterday due to family commitments but joined the Pre-season training with the rest of his team-mates today.
