Denver's offensive-line depth is tested after Nick Gargiulo left Saturday's preseason game with a knee injury against Arizona. Gargiulo, a seventh-round pick from South Carolina (and Yale prior), could miss time, opening questions about the Broncos' interior rotation. The injury adds urgency to how Denver prioritizes its swing-guard/center option and how quickly the team evaluates its 53-man roster plans.

If Gargiulo is out, Luke Wattenberg remains the starter at center, backed by Alex Forsyth and undrafted rookie Joe Michalski. Guards Calvin Throckmorton, Will Sherman, and Clay Webb will compete for snaps. The update underscores how quickly interior-line depth can shift in the preseason and what that means for Week 1 protection schemes and fantasy considerations of Broncos blockers.
