Muhammad Ali, one sports’ greatest legends, is said be in rapid decline, at least according to one person. Ali was last seen looking quite frail at the 2012 London Olympics, and his brother Rahman reports that the champ can no longer speak and doesn’t recognize him. Rahman says his brother’s death could occur in a matter of days.

Confusingly, Rahman also says he has not seen Ali since July and that Ali’s wife, Lonnie, will not allow family to visit. Ali has remained a public figure since being diagnosed with Parkinson’s disease in 1984, including a memorable appearance lighting the torch at the opening of the 1996 Olympics in Atlanta. Lonnie reportedly will not comment on her husband’s condition.
