Brett Favre has been fined $50,000 by the NFL for a “failure to cooperate” with its investigation into inappropriate messages and lewd photos he allegedly sent to former Jets employee Jenn Sterger, a decision her lawyer called extremely disappointing.

The league said Wednesday that Commissioner Roger Goodell “could not conclude” Favre violated the league’s personal conduct policy based on the evidence currently available.

“The forensic analysis could not establish that Favre sent the objectionable photographs to Sterger,” the statement said. “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.”

The decision comes a couple of weeks after Favre’s NFL record for consecutive starts was snapped at 297 and ahead of the season finale for the 41-year-old Vikings quarterback, who will play what may be his last game – if he’s healthy enough.

The NFL said its sole focus was on whether Favre violated workplace conduct policy, not to “make judgments about the appropriateness of personal relationships.”

Favre’s fine will help fund a new training program on workplace conduct around the league, Goodell said.

“It clearly shows that an NFL star player was given preferential treatment and tells all other players that failure to cooperate may cost you some money but will not result in other punishment,” said Sterger attorney Joseph Conway, who added there was “ample evidence” the photos were of Favre.

“Today’s decision is an affront to all females and shows … the NFL remains the good old boys’ league.”
