USC junior forward Nikola Vucevic announced Friday that he has signed with an agent and will forgo his senior season to enter the 2011 NBA draft.

The 6-foot-10, 260-pound Vucevic, 20, averaged 17.1 points and 10.3 rebounds in 34 games for the Trojans in 2010-2011, earning All-Pac-10 First Team honors and leading USC to the first round of the NCAA tournament.

"I just felt like this was the right time for me to leave," Vucevic said. "I made improvements each year, and I think that this year I showed what I can do. I'm ready as a person and as a player. I'm mature enough and it was just the perfect opportunity for me."

"I support, absolutely, what Nik is doing," USC coach Kevin O'Neill said Friday.

By choosing an agent, Vucevic has fully committed to entering the draft.

"I just feel like if you do something, you have to go into it 100 percent," he said. "I felt like testing the waters usually doesn't end up very well."
