From ESPN:
According to ESPN’s “Outside the Lines.” Johnny Manziel signed autographs and memorabilia for dealers in two additional sessions — one in South Florida after the Discover BCS National Championship Game in early January; the other in late January in Houston, Florida-based autograph dealer Kevin Freistat backed and helped organize the additional two sessions, sources with knowledge of the events said. The sessions add to the other four signings reported last week. The NCAA is investigating whether any of the autographs violate NCAA by-laws. Freistat did not return calls or text messages seeking comment. And Manziel was not available for comment either.
