Jeff Green signed a one-year deal for more than the $5.9 million qualifying offer, but has yet to practice this season.

Doctors found an issue during Green's physical and he is undergoing more tests for the undisclosed medical issue.

Danny Ainge said the team is being “cautious’’ with Green.

“We anticipate he’ll be here soon, practicing,’’ Ainge said. “I don’t think very long.

“He’s just going through the tests again, and we should have them and he should be fine. I’m not going to tell you what it is.’’
