The Jets admitted for the first time on Wednesday that they want Brett Favre back in 2009, but the quarterback is questioning his health and has hinted that injuries could force retirement. "I think the pending physical that every player goes through after the last game will shed some light on some things," said Favre, admitting his arm strength might be slipping. He hasn't had an MRI yet, but he has been questioned all season long about a shoulder issue. "It had been hit a couple of times," Favre said. "I don't know, I mean, just knowing my body, there may be something."
