Favre was accused in October of sending graphic photos and sexually suggestive text messages to Jenn Sterger, a female Jets employee, in 2008 (when Favre was the team's quarterback).
"The forensic analysis could not establish that Favre sent the objectionable photographs to Sterger," the NFL said in a statement obtained by the Times. "The review found no evidence to contradict the statements of both Favre and Sterger that they never met in person, nor was there anything to suggest that Sterger engaged in any inappropriate conduct."
However, the statement added, "Favre was not candid in several respects during the investigation, resulting in a longer review and additional negative public the attention for Favre, Sterger, and the NFL," resulting in a $50,000 fine.
Sterger's lawyer, Joseph R. Conway, disputed the NFL's claim of lack of evidence. "To the contrary, our evidence and the personal testimony of Ms. Sterger clearly showed a pattern of lewd and offensive behavior by Mr. Favre that lasted all of the 2008 season," Conway said in a statement.
