Buckeyes star Turner set to announce he's going pro

Ohio State star Evan Turner will announce Wednesday that he's entering the NBA Draft, a source has told CBSSports.com.

A press conference is tentatively scheduled for 4 p.m. ET.

Turner was named the CBSSports.com National Player of the Year after leading Ohio State to a share of the Big Ten title. The 6-foot-7 combo guard averaged 20.4 points, 9.2 rebounds and 6.0 assists this season despite missing six games because of broken bones in his back. He's expected to be among the top three picks and could challenge Kentucky's John Wall for the top overall spot.
