Call Ricky Williams Errick Miron now ... the former Miami Dolphins star announced he's legally changed his name -- saying he made the move, in part, to try to fix an "imbalance" in his marriage with his wife.
Williams -- whose birth name is Errick -- joined “The Dan Le Batard Show with Stugotz” last week ... where he confirmed that he's assumed the last name of his wife, Linnea Miron, following their marriage.
The 45-year-old told the show he made the name change official about a year-and-a-half ago .
