The notice, released in response to public records requests and first reported by The Register-Guard, follows reports that Oregon already met with the NCAA Committee on Infractions last month.
The NCAA has been looking into payments Oregon made to recruiting services, including a $25,000 payment to Willie Lyles and Houston-based Complete Scouting Services in 2011. Lyles had a connection with an Oregon recruit.
University President Michael Gottfredson received the notice of allegations on Dec. 5. Much of what is included mirrors what was in a summary disposition that Oregon submitted to the NCAA last October.
The NCAA will not comment on ongoing investigations. It is not known when a decision might be announced.
