Earlier, Cricket Australia had confirmed that the 24-year old fast bowler will be out of action due to a "bone oedema in his vertebrae" – which in simpler terms means a swelling in the joint, which is not the more serious stress fracture.
CA's Team Physiotherapist, David Beakley had said, "Pat has experienced some back soreness during the fourth Test in South Africa. Follow-up scans have confirmed that he has bone oedema in his vertebrae.
"It is important that Pat has time off bowling, to prevent the injury becoming more serious and consequently we have made the decision to rule Pat out of the IPL."
