Receiver Jerry Rice will retire as a member of the 49ers next week. Rice, who holds most of the significant NFL receiving records, won three Super Bowls during 16 years with the 49ers. He will sign a contract Thursday at the 49ers' training complex before making his retirement official, the club officially announced Saturday. The wideout will be honored again during halftime of the 49ers' game against the Seahawks on November 19.
