ESPN.com's Darren Rovell and Justine Gubar report Texas A&M quarterback Johnny Manziel participated in two previously unreported autograph-signing sessions.

According to Rovell and Gubar, Manziel participated in signings in both South Florida after the BCS National Championship Game in early January and in Houston later that month. They were both organized by Florida-based autograph dealer Kevin Freistat, according to the report.

That brings the total number of paid reported sessions involving Manziel to six. Rovell and Gubar reported Manziel has signed his name more than 4,400 times during the sessions — including more than 1,500 in each of the two sessions organized by Freistat.
