N.C.A.A. Investigates Role of a Recruit’s Adviser

The saga of the nation’s top football recruit, Bryce Brown, and his controversial adviser and mentor, Brian Butler, took some new twists Thursday, with the University of Miami saying it was no longer interested in Brown and the N.C.A.A. beginning an apparently unrelated investigation of Butler.

The assistant director of the N.C.A.A.’s amateurism certification staff, Mike DeCesare, is in Wichita, Kan., investigating Butler, who trains and advises Brown and other players in the Wichita area.
