ENGLEWOOD, Colo. — A person with knowledge of the situation tells The Associated Press the Denver Broncos fear star linebacker Von Miller suffered a season-ending ankle injury toward the end of practice Tuesday.

The person, speaking on condition of anonymity because the team hadn’t addressed Miller’s injury, said the team was awaiting results of an MRI on Miller.

The practice took place indoors because of a snowstorm that struck the Rocky Mountains after a series of upper-90s and 100-degree days.
