Oregon says it has been contacted by the NCAA to provide documentation about its use of a pair of recruiting services.
The NCAA's request comes in the wake of Ducks officials telling ESPN.com the school paid a man $25,000 in the spring of 2010 for recruiting services.
Sources close to the inquiry told ESPN.com that NCAA officials will take a closer look at Oregon's recruitment of running back Lache Seastrunk, a redshirt freshman from Temple, Texas, who was one of the country's most highly recruited prospects in 2010. Specifically, the NCAA is asking what role Texas-based trainer Willie Lyles played in Seastrunk's decision to attend Oregon, the sources said.
Oregon athletic director Rob Mullens said his department called the Pac-10 office Friday morning regarding scouting services that specialize in the identification of potential student-athletes. The NCAA contacted the Oregon's compliance office to request the documents later in the day.
"We have been asked to provide a series of documents by the NCAA and intend to fully cooperate," Mullens said. "I reiterate that it is our belief that the purchase of such services is within the allowable NCAA guidelines."
Documents show the Ducks paid $25,000 to Lyles of Complete Scouting Services in Houston. Lyles has a mentoring relationship with Ducks running back Seastrunk and is also tied to running back LaMichael James, a Heisman trophy finalist.
Both Seastrunk and James are from Texas.
Oregon also paid $3,745 to Baron Flenory of New Level Athletics.
"Most programs purchase recruiting services," Oregon coach Chip Kelly said Thursday. "Our compliance office is aware of it. Will has a recruiting service that met NCAA rules and we used him in 2010."
The NCAA will also look to see if Lyles violated NCAA bylaw 188.8.131.52, which states a student-athlete may allow a scouting service or agent to distribute personal information to a school -- provided a fee is not based on placing the player at a school.
Seastrunk's mother, Evelyn, said Thursday night that she didn't know Lyles received $25,000 from Oregon.
"Willie said he was a trainer," Evelyn Seastrunk said. "Now Oregon says he's a scout? Is he on Oregon's payroll? If Willie Lyles collected $25,000 off my son he needs to be held accountable. The NCAA must find out for me. I don't know how to digest someone cashing in on my son."
The Ducks went 12-1 this past season, falling to Auburn in the BCS title game. They were ranked No. 3 in the final Top 25. James led the nation in rushing with 1,731 yards.
