The 31-year-old midfielder has been struggling with an ongoing heel problem which required surgery and has yet to set a date for his return.
"It's a slow process but every month there is some progression and I'm working very hard," he said. "It means a lot of strength work in the gym and I was back while the boys were off in the summer.
"I then do some light jogging outside and a bit of ball work but I do tend to get a bit of reaction the next day. All I can do is remain positive and keep working hard.
"I want to be training with the lads and competing with them for a place in the team and that's been tough to deal with mentally because this is the longest time I've had out of the game."
