In perhaps their least surprising press release of all time, the Spurs have announced that rookies Luka Samanic and Keldon Johnson have been assigned to their G-League affiliate in Austin. Per the Spurs official press release:
The San Antonio Spurs today announced that they have assigned forward Luka Samanic and guard/forward Keldon Johnson to the Austin Spurs of the NBA G League.
Samanic was selected 19th overall in the first round of the 2019 NBA Draft and is just the fourth player born in Croatia to be drafted in NBA history.
