Joe Gilliam wore #17 for the Steelers.
Erric Pegram wore number 20 for the Steelers in 1995 and 1996.
Ben Roethlisberger from the Pittburgh Steelers.
Mike Webster was the last player to wear the number in 1989. I do not think the Steelers will be giving the number 52 out anytime soon.

Willis Hope "Weegie" Thompson wore #87 for the Steelers from 1984-1989.
Johnny Clement was the only Steelers player to wear #00. He wore it from 1946-1948.
No Pittsburgh Steeler wore the number 9 in 2005. Norm Johnson (95-98) was the last Steeler to wear #9.
One is Troy Polamalu! Go Steelers!!
Pittsburgh Steelers offensive lineman Trai Essex wears number 79.
Dennis Dixon, who played as a quarterback for the Pittsburgh Steelers, wore the number 2 jersey during his time with the team. He is not associated with the number 5 jersey. The number 5 has been worn by other players in the Steelers' history, but not by Dixon.
