The Denver Broncos last saw Patrick Surtain II play on October 26th, a win over the Dallas Cowboys. He has since missed a month of action, but the Broncos have kept winning. It's honestly quite amazing that Denver has managed to win despite not having Surtain in the lineup.
Other cornerbacks like Jahdae Barron and Kris Abrams-Draine have filled in nicely in Surtain's absence, and Denver's secondary is still among the best in the NFL without Surtain, which just goes to show you how outstanding the unit is.
Anyway, Surtain's initial recovery time was a 4-6 week window, and Denver was able to not put him on IR.
