Australia Women's Sevens star Emilee Cherry may be ruled out of the Olympics in Rio due to a hamstring injury.
The influential Aussie player suffered a hamstring injury in training earlier this week.
Cherry scored the second-most points of all players in 2015/2016 Women's World Series with 134, including 22 tries for the reigning champions.
Losing the 23-year-old would therefore be a massive blow for the gold medal favourites' hopes, with coach Tim Walsh revealing she would undergo a late fitness test ahead of the first day's action on August 6.
“On Tuesday, Emilee Cherry did a bit of a decel (deceleration) and got a bit of a hammy twinge,” Walsh told reporters.
“She is looking unlikely at the moment but we will give her a fitness test tomorrow. There is still a fair bit of pain there. Her strength is down.
“No-one likes to see it but it happens regularly.
“We have taught the girls – and they’ve embraced it – just to adapt. If someone can’t play, someone else will stick up the hand and do the job. They’re disappointed for her but fingers crossed she gets through.
“We have two reserves in Brookie Walker and Dom DuToit. I will make a decision on that if it gets to that point.”
