1983-05-27 Marvin Hagler w co 4 (15) Wilford Scypion, Civic Centre, Providence, Rhode Island, USA - WORLD. Referee: Frank Cappuccino. Once the contest got underway Scypion (160) quickly found himself outboxed, and although the challenger had been expected to move in on Hagler (160) to make life difficult for him he was unable to mount any real attacks. In the third Scypion continued to be outclassed, being hit by all manner of punches before picking up a cut on the left eye. Switching from southpaw to orthodox in the fourth, with Hagler pouring in the punches eventually a left-right-left combination sent Scypion down to be counted out with 13 seconds of the session remaining.
While the fight was not sanctioned by either the WBA or the WBC who considered that Scypion was not a worthy challenger for Hagler, it was supported by the United States Boxing Association/International. The said organisation was renamed as the International Boxing Federation (IBF) at their first ever convention in late October. The IBF would continue to support Hagler throughout his tenure.
