Columbia, Mo. Missouri junior Kareem Rush is expected to announce today whether he'll leave early and enter the NBA draft. A written statement from the school Tuesday said Rush would make his announcement at a news conference, which coach Quin Snyder also will attend. The statement did not offer any specifics as to Rush's decision. Missouri sports information director Chad Moller declined to comment on Rush's impending decision, joking that Rush would probably use the news conference to review a Monday night concert performance in Columbia by rap artist Nelly. Rush has said previously he would return for his senior season if he's not projected to be among the first 13 selections in the June 26 draft.
