Gene was drafted in the seventh round of the 1957 NFL Draft by the Browns. He was promptly shifted to the guard position on the offensive line in 1958 to better utilize his speed. He was used as a "messenger" guard by Coach Paul Brown, or a guard that delivered the plays in the huddle, while blocking for Hall of Famers Jim Brown, Bobby Mitchell, and Leroy Kelly. But after three seasons in the league, he broke his leg in 1961 and fractured the leg again later in the season while watching a game from the sidelines.
