The Broncos signed Katsis to the practice squad Monday.
Katsis didn't make the 53-man roster for the Broncos but will stay in Denver as a member of the practice squad. The 24-year-old went undrafted in 2026 after spending two collegiate seasons at Northern Arizona, where he most recently finished the 2025 campaign by amassing 60 catches for 1,016 yards and 10 touchdowns, adding five carries for 109 yards and a touchdown.
