Stanton has not played since fracturing the hamate bone in his left hand on June 26. He had surgery to repair the injury two days later and was expected to miss four to six weeks.
The rightfielder did not join the team in Tampa Bay, where the Marlins begin a three-game series with the Rays on Tuesday evening, but he may travel with the team as they conclude the season in Philadelphia against the Phillies.
Stanton had a minor setback in early September after the first game of his minor league rehab assignment.
The 25-year-old played in 74 games this season, hitting .265 with 27 home runs and 67 RBIs.
