The Broncos signed Fulgham to a reserve/future contract Monday, Aric DiLalla of the Broncos' official site reports.
Fulgham spent the 2021 season split between three different teams' practice squads, the last of which was Denver. He was active in Week 17, though he saw only two offensive snaps. Fulgham will look to make enough of an impression between offseason activities and training camp to make the roster as a depth receiver in 2022.
