The married Minnesota Vikings player hit headlines earlier this month (Oct10) over allegations he texted pictures of his penis to former New York Jets employee Jenn Sterger when he was the team's quarterback in 2008.
National Football League officials have been investigating the allegations and if Favre is found to have violated player conduct policies, he could face suspension and fines.
He is said to have met with the NFL's vice president of security, Milt Ahlerich, last Tuesday (19Oct10) and denied sending any X-rated pictures to Sterger, although he allegedly admitted leaving voicemail messages on her cellphone, according to Fox Television's Jay Glazer.
Sterger's manager, Phil Reese, tells the New York Post she is considering co-operating with the NFL investigation.
He says, "She is strongly considering it, leaning toward it. We're currently in the fact-gathering stage..."
