Fant's absence from Wednesday's practice was attributed to a rib injury, Aric DiLalla of the Broncos' official site reports.
While it's at least encouraging that Fant isn't dealing with an aggravation of the ankle injury that has bothered him in recent weeks, his inability to practice on even a limited basis to begin Week 11 is somewhat concerning. Nick Vannett is currently the only healthy tight end for Denver, so he could be in line for a substantial workload if Fant's injury is serious enough to sideline him.
