In a season full of challenges, Brett Favre has yet another. The 41-year-old Minnesota Vikings quarterback started Sunday even though he's been sick most the week.

Favre took a steroid pack, had an injection Saturday and missed the first hour of meetings because he couldn't get out of bed.

Favre said Saturday night the illness might be pneumonia, but the Vikings medical staff said it thinks he has been suffering from a sinus infection.

After the first week without fired head coach Brad Childress, Favre said he wants to get the magic back the Vikings offense had last year but admits he's not sure that's possible, saying, "It's not like we took the playbook and dumped it in the trash -- although maybe we should."

Favre's dedication helped the Vikings snap a seven-game road losing streak with a 17-13 win. He finished 15 for 23 for 172 yards -- and for only the second game this season, Favre did not throw an interception.
