Jerry Kramer, former star right guard of the Green Bay Packers, will get back his Super Bowl I championship ring, which was lost 25 years ago, his spokeswoman said Monday. The ring showed up on an auction house's Web site last month. The auction house's president will return the ring to Kramer on Tuesday at Lambeau Field, said Jennifer Smith, Kramer's spokeswoman. "We are giving him the ring back," confirmed Doug Allen, president of Mastro Auctions Inc. in the Chicago area.
