The Denver Broncos face a dwindling list of unsigned free agents, now down to three: Michael Burton, Quinn Bailey, and Zach Cunningham. Fullback Michael Burton, 33, has been a key part of the team for two years and is expected to return for the 2025 season. Offensive lineman Quinn Bailey, 29, has also been with the team since 2019 but is recovering from a serious ankle injury and spent the last season on IR. Inside linebacker Zach Cunningham, 30, joined the Broncos after an injury to Alex Singleton but hasn't made a significant impact and is unlikely to return next season.
