Looks like the Wizards star will be fine.
Chris Miller of CSN Mid-Atlantic:
If Wall can play in a preseason game, he can obviously play in a regular-season game. And even if he’s playing reduced minutes now, that bodes well for him being fully healthy in time for the regular season.
The Wizards are at their best with Wall orchestrating the offense and providing first-level resistance on defense. In a crowded Eastern Conference playoff race, they need every full-strength game they can get from him.
