Gordon Hayward is inching closer to traveling with the Boston Celtics, but is still far away from a return to the court.

Brad Stevens told reporters in Detroit Friday that Gordon Hayward is still a few weeks away from traveling with the Boston Celtics, but is continuing to make progress toward running without assistance.

Stevens was asked by the Boston Herald’s Mark Murphy for an update on Hayward and Stevens explained the progress Hayward is making ramping up his training on the Alter-G anti-gravity treadmill, which reduces weight impact on running for athletes with lower body injuries.

“We talked the other day, he’s going to do another Alter-G kind of process or progress starting on Sunday where he goes from 60-percent all the way to 100,” Stevens said, via MassLive’s Jay King. “Once he gets to 100 — or I guess in the Alter-G, 90-95 — once he can do stuff running or jumping, then it makes sense to bring him on the road. It doesn’t look like it’s any time in the next couple of weeks.”

The Alter-G creates a vacuum chamber on your lower body to reduce your body weight as you run on its state of the art treadmill, allowing Hayward to run at 60% of his body weight and significantly reduce the stress on his ankle. This allows Hayward to run sprints and build up his conditioning while his ankle continues to heal and strengthen.

The transition from running at 60% weight on an Alter-G to basketball activities is still pretty massive, so this progress update shows he is still probably months away from playing basketball again. He continues to be making steady progress in his return, but there just may not be enough time left in the season for that return date to line up with the Celtics schedule.
