EDEN PRAIRIE, MN—Though Vikings quarterback Brett Favre confirmed his ailing right shoulder was "no big deal right now" and that the broken bones in his left foot were "uncomfortable but endurable" for the moment, the three-time MVP told reporters Thursday that one more loss could exacerbate his injuries to the point where he would have to retire. "At this level, and at my age, it would take just one game-breaking play—a deep pass, a long run, anything—by the opposing offense to aggravate an injury to the point where I can't go on," said Favre, who later claimed his injuries become more serious with each defeat he suffers. "It's entirely possible for any given team on our schedule to outscore me so badly I can't physically continue my heroic streak of consecutive starts." Favre also added that any victory he led the 3-6 Vikings to this season would be an amazing display of toughness.
