Chandler Parsons scored 24 points, and Dirk Nowitzki added 16 as the Mavericks ended the preseason with a 117-92 win over the Magic on Friday.

Orlando (4-4) didn't help itself, posting a preseason-high 26 turnovers.
The latest news from around North Texas.
Tobias Harris led the Magic with 14 points.
The Magic's played under slightly dampened spirits following news Friday that second-year guard Victor Oladipo would have surgery Saturday for a facial fracture he sustained after catching an inadvertent elbow in practice Thursday.
Oladipo had already missed the entire preseason with a sprained right medial collateral ligament and remains out indefinitely. He joins Channing Frye, who also sat all eight preseason games and is out with a sprained left MCL.
