Aron Baynes has been ruled out of the remainder of the Boomers' Olympic campaign, Basketball Australia has confirmed.
Baynes picked up a neck injury while on court during the second half of Australia's 86-83 win over Italy on Wednesday night.
ESPN's Olgun Uluc first reported the news of Baynes' injury on Friday morning [AEST], before the Australian NBA veteran confirmed his Games were over a short while later.
"I am really disappointed that I can't continue in the Olympics," Baynes said in a statement.
"I along with the rest of the team have been working so hard in our quest for an historic Olympic medal and I am gutted that I can't complete the journey with the boys', but I have every confidence that they will get the job done."
Boomers coach Brian Goorjian said that while the loss of Baynes was a setback, Australia would adapt accordingly.
"Aron is a big part of our team and we are all hurting for him, but we have great depth in our squad and I have every confidence the 11 remaining players. We will all stay focused on the task ahead," Goorjian said.
"Unfortunately, injuries can happen but this team is resilient and we will adapt."
Boomers captain Patty Mills said his side could cover the loss of Baynes, despite the Toronto Raptors centre's position as one of the team's key cogs.
"It's a tough loss for us. His presence on the floor and physical play has been a big part of our identity for so long and that will be missed, but it doesn't change our focus and how we go about our business and what we have come to achieve," Mills said.
"We have always spoken about how important each player's role is, and the impact it can have for the better of our group because of our depth. That doesn't change. We've got Baynsey's back. We'll cover for him.
"I have every confidence in this playing group and our focus will not waiver as we strive for that Olympic gold medal,"
The Boomers face Germany in their final pool match in Tokyo on Saturday night.
