Ten Bronco players wore #60 in franchise history. Seven Offensive Guards, two Centers and a Defensive End. Here are the candidates considered.
Ernie Park was drafted by the Chargers in the 19th round (146th overall) of the 1963 AFL Draft. He played in San Diego for 3 years and the Dolphins for one before joining the Broncos in 1967. Park recovered two Fumbles that year. Ernie played one final season in his career in 1969, with the Bengals.
Joe Burch was drafted in the 3rd round (90th overall) of the 1994 NFL Draft by the New England Patriots, but never played in the NFL. Burch was an Arena League football player that was signed to the Broncos Practice Squad in 1994. He was promoted to the Active Roster for the Week 17 loss against the New Orleans Saints, but didn't play a snap.
