FLORHAM PARK, N.J. — Brett Favre insists he hasn't decided whether he'll return to the New York Jets next season, but says the health of his right arm could be a factor.

The 39-year-old quarterback has struggled for several weeks, with one touchdown and six interceptions. Favre's arm strength doesn't appear to be what it was earlier this season. That has led to speculation his right shoulder may be ailing, and Favre did little to dispel that notion Wednesday.

"During the course of the year, there was numerous times where I'd been asked about my shoulder and it had been hit a couple of times," Favre said. "I don't know. I mean, just knowing my body, there may be something, but there's no test yet to reveal anything."
