Clarkson was acquired by the Lakers for $1.8 million cash in a draft-day trade with the Washington Wizards in June. The University of Missouri combination guard was selected with the 46th overall pick.
In July, Clarkson led the Lakers' summer league squad in scoring at 15.8 points a game. The 6-foot-5, 22-year-old shot 42.4% from the field, 42.1% from three-point range and 88.2% from the line through five appearances.
While the Lakers did not release Clarkson's contract terms, he'll earn the rookie minimum of $507,336 for the coming season.
The Lakers can bring up to 20 players to training camp next month but no more than 15 to opening night on Oct. 28 when the team hosts the Houston Rockets.
