Larsson (illness) didn't practice Monday, Ira Winderman of the South Florida Sun Sentinel reports.
Larsson started Saturday's preseason game against the Timberwolves, posting 14 points (4-15 FG, 0-2 3Pt, 6-7 FT), three rebounds and five assists across 24 minutes. However, he left the game due to an illness and didn't return. The ailment isn't expected to impact Larsson's status for Opening Night, but he's missing out on valuable reps with a new-look Heat squad led by Giannis Antetokounmpo.
