Kawhi Leonard's trade to the Toronto Raptors is on hold because of an NBA investigation into the Los Angeles Clippers. The league is examining whether the Clippers circumvented salary cap rules. The Raptors announced Thursday they will wait for the investigation's outcome. The NBA's probe began in September, focusing on a $28 million endorsement contract between Leonard and Aspiration Fund Adviser LLC. The Raptors and Clippers had agreed on a trade earlier this month. Leonard, a seven-time All-Star, is coming off his highest-scoring season. There is no timetable for the investigation's conclusion.
