Indiana sophomore center Cody Zeller will announce his plans to enter the NBA draft during a press conference Wednesday at Assembly Hall in Bloomington, Ind., at 4:10 p.m., a source told The Indianapolis Star's Bob Kravitz. Zeller is the second Indiana star to declare in less than 24 hours after Victor Oladipo announced his plans to enter the draft pool yesterday.

Both players are considered probable NBA lottery picks and were expected to announce their declarations after Indiana was upset during the Sweet 16 round of the NCAA tournament. However, Zeller's play at times raised questions about whether he's physically ready to compete in the NBA.

At the collegiate level, Zeller was named a second team All-American by the Associated Press and scored 1,157 points in 72 games while playing for the Hoosiers. The center averaged 7.3 rebounds per game over the course of his career.

Indiana went 56-16 with Zeller and made back-to-back appearances in the NCAA tournament's Sweet Sixteen. The Hoosiers won their first Big Ten outright championship since 1993 and were a No. 1 seed in the NCAA Tournament this season.
