Mason suffered bleeding on the brain in the incident and was unable to walk for several months afterwards, but is now back on his feet and waiting for the go-ahead from doctors before he returns to action.
"I am just waiting for my skull to fuse together," he told Sky Sports News. "I had a CT scan a month ago and it isn't quite there yet. We are going to repeat that scan in the near future and measure the rate of healing and go from there.
"Physically I am ready to go back in when it is safe and sensible. It's just a case of a bone healing now, there's no brain damage or anything like that. I am in a positive way.
"I feel fine, I wouldn't put myself in a position that could possibly be dangerous. I am just being patient, respecting my body and letting it heal.
"It was a dangerous collision but credit to the medical team that was there and acted so quickly that I am here now and in a physical condition to return to playing once the skull has healed."
Since his injury, Mason's side have been relegated to the Championship and also have a new manager in the form of Leonid Slutsky.
