The defender has been sidelined with an Achilles injury for three weeks but has now been given the nod to start training again.
The 29-year-old would have been back sooner, and he told the Sheffield Star: "I couldn't believe it, I saw the specialist and was told that my injury could have been treated.
"I think the Achilles was a red herring. I'd actually burst a muscle in my leg.
"It's so frustrating because if they had (the specialists) picked it up in the original scans, then I could have been back playing two weeks ago."
