CANASTOTA, N.Y. — The once-proclaimed “baddest man on the planet” fumbled for words that wouldn’t come. Sylvester Stallone knew exactly what Mike Tyson was feeling.

Both were inducted in the International Boxing Hall of Fame on Sunday, Tyson for his reign as heavyweight champion of the world, Stallone for his “Rocky” movie series.

Thousands packed every corner of the induction grounds, and Tyson was no match for the emotion of the moment.

“I’ve got to be goofy about this or I’ll get emotional up here,” Tyson warned before trying to honor the late trainer Cus D’Amato, who became his legal guardian after Tyson’s mother died and taught him the finer points of the sweet science in a gym in Catskill, N.Y., just a 2-1/2-hour drive from the Hall of Fame.
