The Magic announced Wednesday Hennigan, 30, will replace Otis Smith, who was fired May 21, NBA.com reported.
Hennigan worked as the Oklahoma City Thunder's assistant general manager/player personnel for two years, where he also oversaw college, professional and international scouting departments. He had previously worked as the director of basketball operations for the San Antonio Spurs.
"He's got experience working for championship organizations beyond his years, and from my perspective, this is his time," Magic CEO Alex Martins told the Orlando (Fla.) Sentinel. "He's prepared himself for this opportunity, and the experience that he's gotten from two of the most successful organizations in our league has prepared him to develop and build his own successful basketball operation."
The Magic were to introduce Hennigan at a press conference Thursday.
