UCLA freshman forward Trevor Ariza will declare himself eligible for the NBA draft Tuesday at an 8 p.m. ET press conference.

Ariza will not hire an agent, but UCLA coach Ben Howland says he does not expect Ariza to return to the program.

The 18-year-old Ariza, who made the Pac-10's all-freshman team, is the second UCLA underclassman eying a move to the pros.

Last week, swingman Dijon Thompson, the leading scorer at 14.4 points, said he will declare himself eligible for the NBA.

To be eligible for the daft June 24, an underclassman must send a letter by May 10 to the NBA. A player with eligibility remaining who has not signed with an agent must withdraw from draft consideration by June 17 to return to his college team.

Thompson could return for his senior year. But UCLA has released Ariza from his scholarship, making him eligible to transfer should he decide to return to college.

The 6-7, 205-pound Ariza started 23 of 25 games and was the Bruins' No. 3 scorer with 11.6 points a game and No. 2 rebounder at 6.5 a game.

He also led UCLA in steals, averaging 1.68, had an assist average of 2.1, and shot 42.6 percent, 23.7 percent from 3-point range.
