Boston Celtics centre Aron Baynes is set to miss at least one NBA game with a hamstring injury while fans await an update on fellow Australian star Ben Simmons' back issue.
Boston have confirmed on Twitter that Baynes won't play against Orlando on Tuesday (AEDT) due to a sore hamstring.
Baynes started in the Celtics' win over the New York Knicks on Sunday but left the game early in the second period and did not return.
"I don't have any update on it," Boston coach Brett Stevens said in his post-match press conference. "Hamstrings are scary to me."
Baynes scored 10 points in 11 first-half minutes against the Knicks and has averaged 15 minutes per game early this season.
The Philadelphia 76ers are yet to announce if Simmons will miss any games with the back problem that caused his early exit in the home win over Orlando Magic on Sunday.
Reigning rookie of the year Simmons was withdrawn during the first quarter with back tightness.
Philadelphia were expected to provide an update their young star's fitness after the weekend although coach Brett Brown said post-game that he did not believe the complaint was serious.
"I was told that his back was sore before the game, and they had manipulated it, just for me to be aware of it so I wasn't surprised," Brown said.
"When the game started I was particularly paying attention to him and it didnt feel right or look entirely right and we decided to get him out after making that judgement."
Simmons played 43 and 34 minutes in the 76ers' first two games of the season with their third game coming just five days after their first.
Their next game is at home to the unbeaten Detroit Pistons on Wednesday.
