Hufanga (ankle) did not participate at the Broncos' practice Thursday, Aric DiLalla of the team's official website reports.
Hufanga has missed back-to-back practices to open the week as he continues to work his way back from an ankle injury he suffered in Week 5 versus the Chargers. The safety appears likely to miss a third straight contest, and if that's the case, Devon Key would stand to draw another start in Denver's secondary Sunday versus the Chiefs.
