LYNBROOK, N.Y. (AP) — Trainer Gil Clancy, who guided Emile Griffith to welterweight and middleweight titles, has died. He was 88.

Clancy died early Thursday at an assisted living facility on Long Island, according to his daughter, Patricia Houlahan.

Born in Rockaway Beach, Queens, Clancy boxed in college and in the Army. He earned a master's degree in teaching at New York University and paid tuition by training fighters. Eventually, he rose to prominence as a corner man.

Clancy also worked with Muhammad Ali, Joe Frazier, George Foreman, Oscar De La Hoya and Ken Buchanan. But he's best known for his 20-year association with Griffith.

Clancy is survived by five children, 18 grandchildren, and 19 great grandchildren. His wife, Nancy, died 16 months ago. Funeral arrangements were incomplete, the family said.
