It also said the football program exceeded coaching limits by allowing staff members to engage in recruiting activity.
The NCAA said Kelly was unaware of Lyles’ involvement in recruiting, but the committee noted it is the head coach’s responsibility to know the rules and ensure staff and coaches comply with them.
“I’ve not met an institution that wants to go through the infractions and enforcement process,” infractions committee member Gregory Sankey said. “This was a multi-year effort that certainly existed and there are penalties that impacted the program. The committee made its decisions based on information given to it, not on other speculation and evaluations.”
Under Kelly, the Ducks appeared in four straight BCS bowl games — including a bid for the national championship against Auburn in 2011. Oregon finished 12-1 last season, capped by a victory over Kansas State in the Fiesta Bowl.
He was replaced by offensive coordinator Mark Helfrich, who will make his debut as head coach on Aug. 31.
Oregon was previously penalized by the NCAA in 2004 for a major violation involving the improper recruitment of a junior college player by an assistant coach. The university was put on probation for two years and the unidentified assistant coach was suspended without pay for a week and restricted from some recruiting activities.
The Ducks remained eligible for postseason play and did not lose any scholarships because of that violation, which occurred in 2003.
