Power suffered a concussion and compression fractures of his second and fourth lumbar vertebrae during a practice incident at Infineon Raceway on Saturday.
"It feels great to be home," said Power."I'm looking forward to seeing Dr. Trammell next week and continuing my recovery. I'm feeling better and stronger every day and I really have to say thanks for all the good wishes and support over the last week. We've heard from so many people in the IndyCar community and the fans have been great - they really helped keep my spirits up. I especially want to thank Roger Penske, Tim Cindric and the Penske Racing team for all they've done. It means so much to be part of this team and I wish I could be with them in Chicago this weekend."
