Smith Jr. vs Fonfara HIGHLIGHTS: PBC on NBC - June 18, 2016

In a fight that quickly became a Knockout of the Year and Upset of the Year contender, underdog Joe Smith Jr. went into enemy territory and pulled off a stunning first round stoppage of one of the light heavyweight division's biggest names - Andrzej Fonfara.

Smith - a relative unknown to many boxing fans from Long Island, N.Y. - came in with nothing to lose, and fought like it. He began a stretch of punches that changed his career mid-way through the first round, landing a big right hand in close that floored Fonfara. The crowd in Fonfara's hometown - Chicago - was sent into a frenzy.

When Fonfara regrouped and got up, Smith went for broke, continuing to land clean shots before dropping Fonfara again in the corner. This time, the ref stopped the fight before Fonfara had a chance to beat the count.

Smith improved to 22-1 with 18 KOs with the thunderous victory, and in the process announced himself as a new name to remember in the 175-pound picture.
