The league action Friday came a day after the site posted a video that included below-the-waist photos, said to be of Favre.

Favre’s Minnesota Vikings will travel to New York to play the Jets on Monday.

“We are reviewing the matter,” league spokesman Greg Aiello said when asked about reports that a person alleged to be Favre sent voice mails and pictures to Jenn Sterger.

Asked to respond to the Deadspin report on Thursday, Favre said: “I’m not getting into that. I’ve got my hands full with the Jets and a.m. trying to get some timing down with our guys, so that’s all I’m going to discuss.” Deadspin reported that a man alleged to be Favre contacted Sterger on MySpace and began leaving her voice-mails. The website posted a video of the voice-mails and several pictures allegedly sent to Sterger’s mobile phone.

“Send me a text. Love to see you tonight,” one voice-mail said.

The 26-year-old Sterger, now a TV personality for Versus, has a website that describes her as an actress, model, writer and television host. Her duties during Jets games included introducing the Jets’ dance team, asking trivia questions and making announcements to the crowd.

If the NFL finds that Favre violated its personal conduct policy, he could be fined or even suspended. The league’s policy allows it to punish a wide range of behavior, even that which is not illegal.

Favre, who turns 41 Sunday, and his wife, Deanna, have been married 14 years. He became a grandfather in the spring.

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.” Later Friday, Deadspin reported that Favre also pursued two female massage therapists who worked part-time for the team, according to one of the women. Deadspin did not identify the women, but a Jets spokesman said the team has contact information for the two women and was giving that information to the league. The Jets spokesman requested anonymity because the NFL investigation is ongoing.

The women were two of 17 massage therapists the Jets used during what they called two intensive recovery days in training camp in 2008.

According to Deadspin, one woman exchanged phone numbers with Favre, and the other woman told the website that the quarterback sent “nasty” text messages and invited both women to his hotel room. In an e-mail to The Associated Press, A.J. Daulerio, Deadspin’s editor in chief, declined to reveal the source of the material. He did say the source of the photos contacted him and that Deadspin paid “more than we ever have” for them.

“I was certain about the accuracy of her story, the evidence was presented substantiating that,” he said, “and then as things began to unfold, it appeared more and more likely that this happened. Plus, there will be more.” Vikings coach Brad Childress said he was not aware of the NFL’s investigation or the website’s allegations. Bus Cook, the agent for the three-time league MVP, didn’t immediately return messages.

Jesse Derris, a spokesman for the Jets’ public relations firm, Sunshine, Sachs and Associates, said “we are working closely with the league in their review of this matter.” Deadspin also reported that Jets director of media relations Jared Winley may have been an intermediary between Favre and Sterger. But Derris said Winley “played no role in this alleged incident.”
