He has been discharged from hospital and is now recovering at home in Queensland after undergoing a check up in Brisbane today.
The 29-year-old remains hopeful he will be deemed fit enough to race the #14 BJR Commodore next week.
“I want to race and I will be doing everything in my power between now and then to be ready,” Walsh told Speedcafe.com.
“At this point it is not clear and too early to tell, but I definitely want to race.
“It is a bit of a race against time at the moment.
“I had an off at Turn 1 and I ended up flying through the air before eventually rolling over four times.
“I was airlifted to hospital because they initially thought I had broken one of my legs.
“I had pretty severe back pain and rib pain but I have no breaks so I'm pretty lucky.
“I have just got a contusion on my right lung and very severe bruising everywhere and whiplash.
“They (the doctors) were concerned by some breaks but I have had a CT scan and X-Ray and it doesn't look like I have any, so fingers crossed that is accurate.”
“We are hoping Ash will be ok, he has no broken bones,” Jones told Speedcafe.com.
“We are going to wait until later next week and monitor his progress over the weekend, and then we will make a decision closer to the race as to how we are going to handle it.
“I have no idea who we would use to replace him at this point in time, but our first thoughts are to try and help Ash recover as quickly as possible.
“We have had a talk about (possible replacements) but we are pretty confident he will be ok.
“Obviously we have been thinking about drivers but I haven't called anyone yet.”
