Brazilian 7-footer Lucas Nogueira, a serious candidate to be a first-round draft pick, has decided to enter the NBA draft, sources told Yahoo! Sports.

Nogueira, 20, possesses a 7-foot-6 wingspan and has been an intriguing prospect to NBA executives for several years.
The center initially entered his name into the 2011 NBA draft but withdrew before the deadline. The rules don't allow for a player to do that a second time, so Nogueira is committed to this year's draft.
Nogueira played for Estudiantes in the elite Spanish ACB League in 2012-'13. His athleticism has been a striking element of his game, and Nogueira's offensive abilities have shown improvement as he's gained strength and polish.
Nogueira made a strong initial impression on pro executives with a spectacular performance at the Under-18 FIBA championships in San Antonio in 2011.
Draftexpress.com rates him as the fourth-best international prospect in his age group behind three past lottery picks – Toronto's Jonas Valanciunas, Charlotte's Bismack Biyombo and Utah's Enes Kanter.
