Dallas Mavericks' lead athletic trainer Casey Smith will have a change of roles this season, sources told Tim Cato of The Athletic.

Smith will take on a broader role, reducing his involvement in the team's day-to-day activities.

Smith will no longer sit on the team bench or be in the locker room after games.

The change in roles also adds uncertainty to Smith's position with the team after his contract runs up at the end of this season.
