Here you are, hope this clears it up for you. This is from the NCAA site. The link to the whole article is listed previously in the thread, but this is the answer to why Auburn declared him ineligible, and even though you didn't ask it also explains why he is eligible.
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.
From a student-athlete reinstatement perspective, Auburn University met its obligation under NCAA bylaw 14.11.1. Under this threshold, the student-athlete has not participated while ineligible.?
okay, I'm sure Auburn wasn't aware of this before Monday.
