The Steelers signed Edmunds off the Jaguars' practice squad Monday, Tom Pelissero of NFL Network reports.
Edmunds failed to make Jacksonville's initial 53-man roster in late August but has since found a home in Pittsburgh, where he spent the first five years of his career. The Virginia Tech product appeared in the Jaguars' Week 1 game, recording no stats while playing just six defensive snaps. He's expected to serve as a depth piece in Pittsburgh's secondary as the season progresses.
