WASHINGTON, D.C. -- The NFL appears to be in the final stages of its inquiry into allegations that Vikings quarterback Brett Favre sent inappropriate text messages and photos to former Jets employee Jenn Sterger in 2008 when he was with that team, according to a report from ESPN's John Clayton.

Clayton reports that NFL Commissioner Roger Goodell could rule within a week. At issue is whether Favre violated the NFL's personal conduct policy with the focus being on Favre's conduct in the workplace. Steger, who worked for the Jets as a sideline reporter, has cooperated with the NFL's investigation and last week she and her lawyer provided the final visual evidence, according to ESPN.

Favre, 41, already has been interviewed once and Clayton writes "the expectation is Favre will be re-interviewed to see how his story matches the evidence." It's unclear when or where that interview might take place. The NFL began its investigation after the website Deadspin posted a video on its site in early October that included text messages and voice mails that allegedly were from Favre and included lewd photos. If Goodell decides that Favre did violate the personal conduct policy, he could face a fine or potential suspension.
