Johnson still has to pass a racecourse doctor, but thinks that will be no problem-and he has the prospect of partnering Looks Like Trouble - who showed that he is back to his best with a recent win - in the Cheltenham Gold Cup.
Recalling that horendous fall at Exeter, Johnson said: "The horse in front was swerving about as we approached the jump and I doubt if my fellow saw the fence. It wasn't his fault that we fell. I think he came down on my leg. When I moved slightly the leg did not come with me. It was pretty obvious that I was in some trouble.
"It wasn't particularly painful at that time, which I was surprised at, as I had expected much worse. The real hurt came when they plastered it up that night to prepare for the operation next day. That was really painful.
"In the end I lost about two winners a day (he had ridden 81 until then), and that hurt more than the leg. But I stopped counting because there was no point."
Johnson's comeback will mean less chances for Hobbs's two deputies, Robert Widger and Paul Flynn, who have been making hay while the stable jockey has been out of action.
But they deserve credit for keeping the Somerset yard ticking over nicely since Johnson's absence.
