Highsmith is in the starting lineup for Friday's preseason game against the Grizzlies.
The Heat are resting most of their regulars in the preseason finale since the start of the regular season is right around the corner. Jimmy Butler (rest) is among those out, which means Highsmith, who has had a solid preseason, will get the nod alongside Dru Smith, Pelle Larsson, Thomas Bryant and Nikola Jovic.
