Will the Broncos sign a 4th quarterback after Bo Nix surgery?

While speaking at the NFL's annual league meeting in Arizona last month, Denver Broncos owner Greg Penner, general manager George Paton and coach Sean Payton all indicated that quarterback Bo Nix was ahead of schedule in his ankle recovery and on track to participate in the team's spring offseason program.

Just under one month later, Nix underwent what has been described as an "expected," "anticipated" and "planned" clean-up procedure last week. After undergoing that follow-up procedure, NFL Network's Ian Rapoport indicated Nix is expected to be ready for the start of training camp.

Denver's brass (and the QB himself) had previously indicated Nix was on track for organized team activities (OTAs), but if Rapoport's timeline is accurate, Nix returning for training camp would see him back on the field in late July, not this spring.

If Nix is not available for OTAs and mandatory minicamp in June, the Broncos would be down to two healthy quarterbacks in and . Even though it would be lighter sessions than training camp, Denver might consider bringing in a fourth-string "camp arm" to serve as QB3 if Nix is sidelined this spring.
