CANASTOTA, N.Y. (AP) — Mike Tyson broke down in tears and cut short his speech while Sylvester Stallone proclaimed “Yo, Adrian, I did it!” as the two stars from different fields were inducted into the International Boxing Hall of Fame on Sunday.

Mexican champ Julio Cesar Chavez, Russian-born junior welterweight Kostya Tszyu, Mexican trainer Ignacio “Nacho” Beristain and referee Joe Cortez also were inducted.

Tyson tried to honor the late trainer Cus D’Amato, who became his legal guardian after Tyson’s mother died and taught him the sweet science. But his eyes welled with tears and he apologized and walked away from the dais after only a moment or two.

The “Rocky” movie series, which began in 1976, made Stallone what he is today and also captured boxing’s heart for decades. The actor wrote the script about an underdog boxer from Philadelphia named Rocky Balboa and then played the part in the movies.

Posthumous honorees enshrined included: bantamweight Memphis Pal Moore, light heavyweight champion Jack Root and middleweight Dave Shade in the old-timer category; British heavyweight John Gully in the pioneer category; promoter A.F. Bettinson; and former BBC broadcaster Harry Carpenter.
