The inspirational captain of Sydney's Kevin Lisch is competing with the time to be passed for the Kings heavyweight battle with NBL champion Melbourne United.
Lisch injured his jaw in a training clash with team-mate Dane Pineau a day before Sunday night won 100-87 home over New Zealand Breakers.
Reliable back-up guard Kyle Adnam received a nod to start on his 25th birthday in Lisch's absence and played an integral role with 14 points in Sydney's fifth win of eight matches.
The kings who finished third crossed their fingers twice NBL MVP Lisch back for Saturday's battle with second place in Melbourne.
"He got a bad attack on his jaw. I didn't think it was a concussion, but of course as soon as the doctor said he could not play, we did not argue," Sydney coach Andrew Gaze said.
"He will train on Tuesday. He will not make contact but he will do all the matches.
"He will do training again on Wednesday and then do a full session on Thursday and we expect him to play.
"He might eat soup three or four days later. He might not be able to chew but as long as he can shoot and survive.
"But if the doctor says no, there is no debate. They determine 100 percent what he can do."
Stares aren't surprised Adnam handles his promotions easily.
"Kyle has been a victim of more than anything and, in many teams, he will get more opportunities," he said.
"He may have to play more, but he plays his role very well. This is a compliment to Kyle that he is ready to sacrifice for the good of the team."
Jerome Randle led the Kings with 24 points, while Andrew Bogut was dominant at both ends of the field with 15 points, 10 rebounds, seven assists and five blocks.
"This is not only what he (Bogut) does statistically. He provides excellent leadership and that generates a lot of trust among people," Gaze said.
"Even the shots he didn't destroy, people will think of him because he came from somewhere."
