FAVRE FOLLIES: NFL Commissioner Roger Goodell said once the league completes its investigation of allegations Brett Favre sent racy messages and lewd photos to a Jets game hostess in 2008, it will "make a determination" if the Vikings quarterback should be punished.

Goodell added once the investigation is complete, "we'll make a determination from there."
