Kurtley Beale suffered a suspected ruptured Achilles tendon on Saturday, shortly after Wallabies management agreed to the 35-year old's request to be given more playing time for club side Randwick after missing the first half of the 2024 Super Rugby Pacific season.
Beale was one of 38 players attending Australia's Test camp last week in Brisbane ahead of selection for the opening two internationals of the home season against Wales.
The decision to let Beale play in Sydney's Shute Shield is set to jeopardise his chance of more Tests against Georgia, New Zealand, South Africa and Argentina after the seemingly innocuous incident in front of a few thousand fans against Eastern Suburbs.
The Wallabies permitted the Darug and Gomeroi man on Friday to fly home from the camp after he was unsigned for early parts of the 2024 Super Rugby competition while facing a sexual assault trial, in which he was found not guilty, that had also seen Beale to abandon the entire 2023 season with NSW Waratahs.
Beale was included in the Test squad after impressing from a restricted number of games for Western Force this year, but the playmaker still felt he was underdone ahead of selection for next week's opening Test in Sydney.
The sudden injury occurred behind play and was not captured by TV cameras streaming the game at Woollahra Oval, but the venue has had past complications from the initial installation of its synthetic pitch.
It is believed Beale was moving back into a defensive position towards receiving a kick from Easts when he twisted his leg and fell to the ground.
He went down in 59th minute after coming into the game in the first half, later left limping off the ground with the aid of both medical staff and a Galloping Greens teammate.
Easts had sought compensation from Woollahra council back in 2018 over the quality and completion of the high-tech artificial surface.
The project that began in September 2016 hit a major hurdle when workers had to rip up the surface that replaced the turf and start over.
There is no suggestion that synthetic surface was a direct cause for Beale's injury - that could take up to nine months to fully recover - but players not used to the artificial grass often say it does not have the same give as natural turf.
There has been no full medical assessment over the weekend, but Beale will probably be out of the rest of the season.
A spokesperson for Rugby Australia said Beale would head in for scans on Monday.
The injury could now end the big-picture objective of Beale being the first Indigenous player to reach 100 Test matches for Australia.
The Force fullback played the last of his 95 internationals in 2021 against Scotland.
"It's a huge milestone within the game," Beale said at the Wallabies press conference six days before his injury.
"You almost dedicate the game, coming straight from school, always being a part of my life like forever now.
"These are little things that are huge motivators for me. It allows me to have that real purpose.
"It allows me to get up and go to training every day with a real strong purpose and intent to be able to go out there and go for it."
New Wallabies coach Joe Schmidt has given no indication publicly whether Beale was in contention for a spot, but his versatility to play fullback, inside centre or five-eighth gave the oldest man in the squad a chance to play off the bench to cover multiple positions.
The injury may help winger Dylan Pietsch's odds of becoming the 15th Indigenous Wallabies player, with utility back Tom Wright probably set to settle into the fullback role instead of Beale while Pietsch, a Wiradjuri man, could fill the hole in either the final run-on side or coming off the bench.
But there was also media speculation online that Beale was told privately that he would not be playing against the Welsh next weekend anyway.
While the next World Cup is still three years away and Beale would be 38 by that stage, he has indicated that featuring in the British and Irish Lions Test series is another key goal.
But spending this year and next year's preseason on the sideline would leave a major dent in his future international ambitions to face arguably the biggest challenge in world rugby.
"I think I've mentioned a big carrot would be part of (having) another crack at the British and Irish Lions tour," Beale said last week.
