Jenn Sterger (Personal Photo)
NEW YORK (CBS/AP) Gawker sports blog Deadspin called it "Brett Favre's Cellphone Seduction of Jenn Sterger," when they released voicemails and X-rated pictures that they say feature the Minnesota Vikings quarterback, and now the NFL is investigating.
NFL Commissioner Roger Goodell says the league will "make a determination" if the Vikings quarterback should be punished once the NFL completes its investigation.
The NFL is looking into the matter under its personal conduct policy.
Crimesider spoke to CBS News legal analyst Trent Copeland, who said that even though "Favre is a hall of fame-caliber quarterback, at the end of the day, he's an employee." And just like any other employee, he's supposed to follow the rules and regulations of his employer, especially regarding the treatment of other employees.
The texts were allegedly sent by Favre to Jenn Sterger, then a sideline reporter employed by the New York Jets, while Favre played for that team. The Vikings, Favre's current team, play the Jets Monday night in New York.
Goodell said that the NFL is "making sure we understand all the facts," speaking at halftime of the Chargers-Raiders game Sunday.
While Deadspin initially reported that Sterger herself told them about the photos last February, the website said that the new evidence was "acquired from a third party."
"Sadly, Jenn is still reluctant to talk on the record about the matter," wrote Deadspin editor-in-chief A.J. Daulerio.
Favre has been married to his wife, Deanna, for 14 years.
Sterger's website describes her as an actress, model, writer and television host. The 26-year-old is now a personality for Versus, a sports-oriented cable channel.
Sterger's manager Phil Reese said she is "not doing any interviews or commenting at this time," but that "Jenn did not provide Deadspin with any information."
