At least, from the way I read the story, his goal is like right about 3 months (AZ races Oct 24/25). Thats about what it seems to take to properly heal the vertebrae (people that come back sooner than that cause me concern). But, depending on his healing process there would be restrictions on the rehab he could do along the way. I wish him the best! He is a tough old school style racer; so I'm sure he will make a great come back when he is ready.
