Katsis signed with the Broncos as an undrafted free agent Friday.
Katsis was dominant for Northern Arizona of the FCS last season, and he recorded a combined 95 receptions for 1,566 yards and 12 touchdowns over his last two college campaigns. He earned All-Big Sky First Team honors as a wide receiver and as a kick returner, as he averaged 30.6 yards per kick return while scoring once. The Broncos have a deep receiver corps, so Katsis likely will need to produce immediately as a returner to earn a 53-man roster spot.
