re: CBS reporting the Cecil Newton admits to soliciting payments

Everyone is assuming the only penalty the NCAA would impose is a forfeiture of the games Newton played in. What are the rules? If Auburn knows Newton is ineligible (because of an admission) and allows him to play anyway, wouldn't they need to be concerned about additional penalties, e.g. probation, loss of scholarships, etc.? If I were Auburn's counsel faced with an admission by the father I would advise them to not play Newton.
