Jerry Rice signed a one-day contract to retire with the San Francisco 49ers on Thursday, officially ending the receiver's matchless career back where it began. Rice, who played the first 16 of his 20 NFL seasons with San Francisco, shed no tears during a short signing ceremony at the 49ers' training complex. The receiver wore his ring from the 49ers' 1989 Super Bowl championship team on a chain around his neck as he hugged his wife, Jackie, and shook hands with San Francisco owner John York. "I would like to put the uniform on and run on that football field, but I think it's time to move on," Rice said, gesturing toward the practice fields behind him. "I feel welcome here. I feel like this is my home, and this is something I'll never forget."
