"The NCAA has alerted us to an issue that could affect Cliff's eligibility," Kansas athletic director Sheahon Zenger said in a statement. "As a precautionary measure, Cliff will not take the court until we have resolved the issue."
Not really sure what else there is to say right now. Cliff has been struggling lately, but Good Cliff means Good Kansas, and KU probably needs him eligible for a deep run in March. Hopefully KU and the NCAA can get this ironed out. I'm sure more information will be coming along in the next few days.
Last year, Alexander's high school team was stripped of all its wins and its championship. Per a report by the Chicago Sun Times, seven players, who were not named, were deemed academically ineligible following a Chicago Public Schools investigation.
“A district investigation into the academic eligibility of members of the Curie varsity basketball team found that a number of the players are academically ineligible to compete and, as a result, their season must be forfeited" said Chicago Public Schools CEO Barbara Byrd-Bennett in a statement last year.
I don't know if the two are related or not, but I would guess that there's a correlation. Time will tell.
