The 41-year-old quarterback will face another tough test in just a few days.
Favre will meet with NFL security officials on Tuesday to discuss allegations that he sent inappropriate messages to a game day hostess while both worked for the Jets in 2008.
"I don't expect anything. ... I'm concerned about the next game," Favre said after throwing for 118 yards and a touchdown against the Cowboys. "I'll let that take its course."
Commissioner Roger Goodell said on Saturday that Favre will meet with a member of the league's security team this week. At issue are allegations made in a report by the website Deadspin accusing the married Favre of pursuing Jenn Sterger with voicemails, text messages and lewd photos.
Sterger has not commented and the website acknowledges there is a possibility that the messages may not be from Favre.
Favre has not commented directly on the allegations, instead steering any questions about it back to the field, where the Vikings (2-3) squeezed out a much-needed win. They head to Lambeau Field next weekend to face the Green Bay Packers, the team Favre spent 16 seasons starring for before leaving in 2008.
"I'm a little bit reluctant to say I'm excited to go back to Green Bay," said Favre, referencing what is expected to be a difficult game. "It's a challenge that hopefully we'll live up to, and I'll let that other stuff take care of itself."
Despite being listed as questionable with elbow tendinitis, Favre started his 290th straight game. Everyone expected the NFL's iron man to extend his record starts streak, even after watching him clutch his right elbow in pain against the Jets last week and miss two days of practice leading up to a needed win against the Cowboys.
He received a cortisone shot early in the week to help with the pain and inflammation in his elbow, then said he felt great after resting on Wednesday and Thursday.
"It seems to have helped," Favre said.
Favre appeared to hold the ball a little too long on several occasions and the offense delivered another disjointed performance with just 188 total yards.
He was crunched by Igor Olshansky early in the third quarter and got up grabbing his ribs. As usual though, the old man stayed in the game and played every snap. Favre said he just got the wind knocked out of him and coach Brad Childress said the punishment he took was nothing extraordinary.
"We're paying him enough every game," Childress said. "He's going to get hit."
Favre's teammates say that they haven't sensed any lack of focus from their leader since the controversy first started swirling about 10 days ago.
"I see a guy who is out there and just focused," running back Adrian Peterson said. "He's fighting through adversity, on and off the field. He's a great leader out there and he is leading the team. He's making plays and he is doing his job well."
Favre continued to insist that the allegations have not been a distraction for him.
"There's nothing like a win," Favre said. "I could care less if I throw for 400 yards, that was as good of a win as any. Hopefully we build off this. I don't feel any added pressure. I mean the fact that we were 1-3 was enough."
