Boston Celtics forward Gordon Hayward said it has been therapeutic to be back with his teammates after the gruesome ankle injury that's expected to sideline him for the remainder of the 2017-18 season. Simply engaging in light shooting from a chair on the practice court this week has helped rally his spirits. "It's going to be really important for me and my mental health to stay involved and still be a part of the team as much as I can," Hayward said at a news conference Thursday. Hayward fractured his ankle just five minutes into Boston's season opener last month in Cleveland. He said it will help "as much as I can be out there on the court with them. I can be with them in the locker room and I can see different things watching the film that maybe they can't see out on the court and I can try to help them. Like I said, that will help me as well." Hayward reaffirmed that there is no timetable for his recovery from surgery that repaired the fractured bone and damaged ligaments, but he wrote in a lengthy blog post Wednesday that he expects to miss the entire season. Hayward, who recently shifted from a hard cast to a walking boot, said he's hopeful he can sit on the bench at Celtics games once the medical staff gives him clearance later in the season. Hayward, who signed with Boston after seven seasons with the Utah Jazz, started coming to the Celtics' practice facility this week for rehab exercises. He also was on the court to take shots from a chair.
