"I am just waiting for my skull to fuse together," the 26 year old told The Debate on Sky Sports Premier League.
"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."
Mason was back in non-contact training with his Hull team-mates over the summer but is not yet ready to engage in more physical training that may hamper his recuperation.
"Joining in with the boys, jumping for headers and being involved in that contact type of training," Mason added when asked what the next stage in his recovery would be.
"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."
