He knocked out Robert Bell at 49 seconds of the first round before a crowd of 14,369, including a hearty contingent of Fighting Irish fans, in the 15,000 capacity arena. Zbikowski first knocked him down with a flurry, and when Bell got up, Zbikowski ran across the ring and hit him with a right hand. Bell spun around and referee Arthur Mercante Jr. stopped the bout. The matchup of Zbikowski against Bell, an Ohioan and Ohio State football fan, was only one in an abundance of cultural clashes on Saturday's Garden card. .
