"The first thing you want to do is find out the facts, and that's what we're trying to do," commissioner Roger Goodell said. "Once we determine those facts, then we'll determine what the next step is from there, if any."
Last week, the website Deadspin posted a story that included several voicemails allegedly sent by Favre to Sterger. The voicemails include a man asking to meet with Sterger, now a TV personality for the Versus network.
The website posted a video that contained the voicemails and several graphic photos - said to be of Favre - that were allegedly sent to Sterger's cell phone.
Sterger's manager, Phil Reese, has declined to say if his client is cooperating with the NFL or has a lawyer.
Deadspin's Terez Owens reported on Monday that Sterger will be let go by Versus and that the former Playboy model has been contacted by the magazine for a second shoot.
Deadspin also reported that Favre pursued two female massage therapists who worked part-time for the team. Deadspin did not identify the women, but a Jets spokesman said the team was giving contact information for the two women to the league.
Hard to believe
Jacksonville has scored 107 points. New Orleans, which led the league in scoring three of the last four years, has scored 99 points.
Chicago quarterback Todd Collins completed six passes and threw four interceptions Sunday, and the Bears still beat Carolina by 17 points! Maybe that's why the Panthers are 0-5.
You're on the air
Versus, which most fans couldn't identify ("Is that a channel that plays music one verse at a time?") is getting free publicity by the truckload right now.
The T.Ocho Show - a talk cohosted by Terrell Owens and Chad Ochocinco - will debut on the network on Tuesday night.
Owens, as usual, isn't bashful. Asked if he's in danger of being overexposed, the receiver said, "With the two of us, I don't think you can really get enough of us."
I'm in charge
New England coach Bill Belichick downplayed talk of a dispute between quarterback Tom Brady and Randy Moss having led to last week's trade of the receiver to Minnesota.
"Tom doesn't make personnel decisions," he said.
