Stewart sprained his right ankle in the team's third preseason game Aug, 26 and hasn't practiced since.
Although he was held out of practice, Rivera says Stewart "moved around very nicely" during a private workout Monday. Rivera says that's a "very encouraging sign" and he's hopeful Stewart will return to practice Wednesday when the team continues this week's game preparation in Bradenton, Fla.
The Panthers were scheduled to fly out of Charlotte Tuesday to avoid scheduling conflicts with the Democratic National Convention in Charlotte.
