Houston Rockets stars James Harden and Russell Westbrook have not travelled with the team to Orlando and did not participate in the side's first practice ahead of the NBA's restart.
Rockets coach Mike D'Antoni did not provide a reason for their absence but said he expects both players to join the team in Florida soon.
D'Antoni explained: "I don't think it's going to be too many days. It will work itself out. Some things you can't control totally, but in a few days, they'll be here.
"It's not ideal. But it's going to be good and we'll be ready to go. It won't set us back."
Houston's first game following the NBA's restart is on July 31 against the Dallas Mavericks, live on Sky Sports.
The NBA returns to your screens on Sky Sports this month as the 2019-20 season resumes at Walt Disney World Resort in Orlando, Florida on July 30.
