Before each season, NBA G League teams hold open tryouts, searching for local talent to add to their rosters. Each team can then invite up to four players from its respective tryout to training camp that fall. The tryouts represent the first step in the extensive process of putting together an NBA G League roster for the upcoming season.
Below is a list of the locations and dates of each NBA G League team's local tryout.
