The Steelers signed Williams to their practice squad Tuesday, Aaron Wilson of ProFootballNetwork.com reports.
Williams signed with the Broncos as an undrafted free agent out of Tennessee Martin, but he was waived ahead of the 85-man roster deadline. However, the 6-foot-4 tight end will extend his NFL dream by attempting to carve out a role on Pittsburgh's practice squad. During his final collegiate season, Williams caught 29 passes for 417 yards and three touchdowns.
