Former Australian captain Steve Smith expects to be cleared to play in the opening Test of the Pakistan tour despite recently exhibiting vertigo symptoms.
Smith's symptoms arose after knocking himself out during Australia's recent T20 series against Sri Lanka on home soil.
While struck with dizziness and nausea, previous head knocks across the course of his career have led the New South Welshman to become familiar with such complaints.
"I think I actually knocked myself out for a couple of seconds there," Smith of his failed catching effort.
"Then, then when I came to, I was in a bit of a weird state and I knew straight away that I was likely concussed after having quite a few knocks to the head.
"It was just headaches, a bit of drowsiness and then a couple of Fridays ago I had a vertigo incident where I was struggling for a bit that day."
Since landing in the sub-continent, Smith has taken part in training sessions with the rest of Andrew McDonald's squad and has claimed he is "feeling good" weeks after being rendered unconscious at the SCG.
"I've been able to do all the exercise stuff that I've needed to do to get myself back to that ready-to-play state.
"I've done a lot of stuff where I've got my heart rate up to a good amount, brought it back down and that's part of the protocols to getting back to playing.
"I had a couple of good hits in Melbourne before we came away, but today's just about ticking off facing fast bowling and once that's done everything should be fine."
Despite padding up in Rawalpindi, the 82-Test extraordinaire only faced spin and side-arm options.
However, Smith will be subjected to a barrage from Australia's quicks ahead of Friday in what is expected to be his final fitness test.
The first of three Tests will commence in Rawalpindi on Friday, March 4 at 4:00pm AEDT.
