Just posted on the NCAA Website:
Auburn University football student-athlete Cam Newton is immediately eligible to compete, according to a decision today by the NCAA student-athlete reinstatement staff. The NCAA concluded on Monday that a violation of amateurism rules occurred, therefore Auburn University declared the student-athlete ineligible yesterday for violations of NCAA amateurism rules.
When a school discovers an NCAA rules violation has occurred, it must declare the student-athlete ineligible and may request the student-athlete’s eligibility be reinstated. Reinstatement decisions are made by the NCAA national office staff and can include conditions such as withholding from competition and repayment of extra benefits. Newton was reinstated without any conditions.
