Australian batting mainstay Steve Smith, whose fitness became a cause of concern after he missed a training session on Tuesday, returned to the nets and batted for some time to prove his fitness on Wednesday. Putting rest to doubts over his participation in the historic first-ever day-night Test between India and Australia in Adelaide, Smith batted for a few overs in the nets session. He displayed his arrow of strokes and showed his trademark resilience during his outing. <p></p> <p></p>After doing a few stretching exercises and running drills at the Adelaide Oval, Smith had skipped the routine football session and headed straight to the dressing room in some discomfort. The day-night Test against India starts on Thursday. Meanwhile, Australia captain Tim Paine said it was not a serious niggle and a day's rest came as a 'blessing in disguise' for the star batsman. <p></p><h2>WATCH VIDEO</h2> <p></p><blockquote class="twitter-tweet"> <p></p><p dir="ltr" lang="en">Steve Smith was back doing what he does best on the eve of the first <a href="https://twitter.com/hashtag/AUSvIND?src=hash&amp;ref_src=twsrc%5Etfw">#AUSvIND</a> Test in Adelaide.</p> <p></p>More: <a href="https://t.co/WcuxdeMnfM">https://t.co/WcuxdeMnfM</a> <a href="https://t.co/k9R0jTvVHj">pic.twitter.com/k9R0jTvVHj</a> <p></p> <p></p>cricket.com.au (@cricketcomau) <a href="https://twitter.com/cricketcomau/status/1339089769087651842?ref_src=twsrc%5Etfw">December 16, 2020</a></blockquote> <p></p>"We expect Steve to be there. He has had a stiff back a number of times before and you can have that if you bat as much as he does at the nets," Paine said at the pre-match media interaction in Adelaide. <p></p> <p></p>"He has a stiff back before and yesterday was more precautionary. Obviously, come tomorrow, he gets through stiff back and finds a way to score runs like he always does," he added. <p></p> <p></p>Australia have already been hit by multiple injuries, with David Warner - groin - and Will Pucovski - concussion - ruled out of the opening Test. <p></p> <p></p>Promising all-rounder Cameron Green, who will make his Test debut on Thursday, suffered a mild concussion after being hit on the head by a shot from Jasprit Bumrah in the pink-ball warm-up match between India and Australia A in Sydney.
