Graner first served as color commentator for the Cleveland Browns from 1955–1960, working for radio stations WTAM and WGAR (AM) alongside Bill McColgan. He is best remembered, however, for his work alongside Cleveland play-by-play announcer Gib Shanley: the two paired-up as the voices of the Browns radio network from 1963–1974, working for stations , and later WHK. Among their highlights: coverage of the 1964 NFL Championship Game, the last major title won by a professional sports team in Cleveland. Immediately following Cleveland's upset victory over the Baltimore Colts at Municipal Stadium, Graner was the man on the field who interviewed franchise owner Art Modell (who, ironically, later moved the team to Baltimore in 1995 — much to the ire of Cleveland Browns fans).
