Joe Gilliam wore #17 for the Steelers.
Erric Pegram wore number 20 for the Steelers in 1995 and 1996.
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.
Ben Roethlisberger from the Pittburgh Steelers.
Lynn Swann wore #88 for the Steelers from 1974-1982.

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.
