In the 24th over on the first morning of the match, Weatherald chased a cover drive from Ollie Peake to the rope and dove head first to try and pull it back.
He was unsuccessful and was unable to stop himself as he rolled onto his side and then his back as he kept sliding metres past the rope, which was well off the fence, before hitting the back of his head on the base of a metal advertising hoarding that was on the boundary pickets.
Weatherald was helped up immediately by a team-mate and did not appear to suffer any initial effects. He fielded the remainder of the day and also came out to open the batting when South Australia had to face an eight-over stint at the end of the first day after bowling Victoria out for 244. He did not survive more than six balls as he edged Victoria debutant Harry Hoekstra to the wicketkeeper for a duck.
On the morning of day two, Weatherald was subbed out of the game after having experienced concussion symptoms overnight.
Weatherald will now undergo monitoring and will need to be symptom-free for a period of time before he’s eligible to play again, which will mean he will be touch-and-go for South Australia’s round two Shield match against Queensland in Adelaide starting on October 19.
It’s a tough start to his return to South Australia after being dropped from Australia’s Test side in August, having scored just one half-century in 12 innings across his first six Tests. Weatherald had thumped 92 in his only One-Day Cup innings for South Australia prior to his Shield return.
