In Creed, what is the name of Adonis Creed's boxing opponent in the opening professional bout?

In Creed, Adonis Creed’s opening professional opponent is Leo “The Lion” Sporino.

The bout takes place in Philadelphia after Adonis leaves Los Angeles and asks Rocky Balboa to train him. Sporino is a local boxer and the son of Pete Sporino, who runs Front Street Gym. The fight establishes Adonis as a serious but still developing professional.

Adonis wins the contest, but his career quickly becomes more demanding when he is offered a shot at world light-heavyweight champion Ricky Conlan. That later fight receives far more publicity because Adonis is Apollo Creed’s son.

Sporino is sometimes confused with Conlan because both are opponents in Creed. The distinction is important: Leo Sporino is Adonis’s early Philadelphia opponent, while Ricky Conlan is the champion he faces at the film’s climax.
