From Liz Williams:
Chris had a problem with his lungs which has led to him being transferred back to the critical ward.
He is in the best care possible, and the physios, doctors and hospital staff are working with Jan to try to get him to breathe properly.
While Jan really really appreciates everyones support, she is asking at this time for visits to be kept until he is out of the critical ward. Keep the support coming via the blog, and doing things around the track etc.
Keep tuning in to the blog for updates, keep up the positive vibes!
