PHOTOS: Atlanta Hawks vs. Cleveland Cavaliers

The Oklahoma City Thunder are trading reserve guard Aaron Wiggins to the Atlanta Hawks for two second-round draft picks, according to multiple reports on Sunday night.

Veteran guard CJ McCollum, who helped lead the Hawks to the playoffs after a January trade, will remain in Atlanta after agreeing to a one-year, $21 million contract extension, multiple outlets reported on Sunday.

The Hawks endured the second-worst postseason defeat in franchise history. The then-St. Louis Hawks lost 133-75 to the Minneapolis Lakers on March 19, 1956.
