Retired quarterback Brett Favre mailed his throwing arm to the Vikings Tuesday, sending the record-setting limb to the team's headquarters for evaluation in hopes of signing with Minnesota. 'I made sure to bubble-wrap it, and I stuck a couple big chunks of dry ice in the envelope, so it should be fine,' said Favre, who sent the appendage after the Vikings expressed health concerns with the potential signing of the 39-year-old quarterback. 'Once the Vikings examine it, I'm sure they'll find that my throwing arm has no structural damage. The doctors who cut it off said it looked great.' According to James 'Bus' Cook, Favre's agent, the three-time MVP is unlikely to come out of retirement if the Vikings believe that his amputated throwing arm will require major surgery.
