"It's clear that the clock is ticking and multiple considerations involved, not only the physical problem, but other factors as well," he commented.
"It's positive. We firmly believe that he's going to play a major part. Hopefully starting in Perth. Should that not happen, then we'll pick it up."
Past Concerns

Backup Options

"We put so much time has gone into developing the strategy for him to be available for the first Test as an batting and bowling option," the selector detailed.
"He was only going to play the starting games anyway. His aggressive style the bat in limited-overs, if it causes any delay for a short period, the choice was made to take a cautious route."
