Denver Broncos linebacker Von Miller suffered a potentially season-ending ankle injury in practice on Tuesday, per Ian Rapoport and Mike Garafolo of NFL Network.
Per Rapoport, the injury is a "serious one" and that "it's not good" based off an initial evaluation. However, more will be known Wednesday following an MRI.
Miller reached his sixth straight Pro Bowl in 2019 but had a somewhat down year by his high standards. His eight sacks were the second-fewest of his career.
Miller's performance mirrored that of the entire Broncos defense. Denver ranked fifth in defensive efficiency in 2018 but slipped to 13th in 2019.
