AMHERST - Ryan Carter doesn't know who the boy is, where he lives, or                        almost anything else about him. He knows only that the 5-year-old is sick                        and Carter, a third-year sophomore defensive back for the University of                        Massachusetts football team, today will do what he can to save his life.                                             
                                            Like almost every member of the Minutemen, Carter is registered as a                        potential donor in the National Bone Marrow Registry. The Maryland native                        didn't think much about it when he swabbed the inside of his cheek two                        years ago as part of the annual drive by UMass to sign people to the                        registry.                      
                                            "At first I was shocked. Is this real? Did I really get chosen?" Carter                        said. "Then I started getting almost excited. I get to save somebody's                        life. I get to be a part of helping this young kid live. ... There's seven                        billion people in the world and this one person needs something that I                        have. It really opens your eyes that this person could live or die                        depending on me."
