The highest number a quarterback can wear in the NFL is 19, which was worn by Johnny Unitas, who played for the Baltimore Colts.-----The highest jersey number that I can remember was #60 worn by Otto Graham of the Cleveland Browns of the All-American Football Conference. John Hadl of the Chargers and Rams wore #21 during his career in the 60s and 70s. But since the merger in 1970, the highest number a quarterback on the roster can wear is 19.
