"Right now I'm 50-50," Green said. "We'll know in the next couple of days and I will make my decision on Sunday.
Green, who has already worked out for Toronto and Cleveland, has battled injuries since deciding to 'test the waters.'
"I think I did a lot better than I did in Orlando," Green said Wednesday, referring to his injury-plagued performance at the Pre-Draft Camp earlier this month. "I'm a lot healthier now. My ankle is feeling a lot better and I shot the ball pretty well."
The deadline to withdraw his name from the NBA Draft is June 16.
