UPDATE (Monday, 12:30 p.m. ET): An MRI Monday revealed a torn ACL for Von Miller, according to multiple reports. Miller is done for the season.
Miller's impact on the Denver defense is almost immeasurable. Despite playing in just eight-plus games, he has racked up six sacks this season and is second on the Broncos with 28 QB hurries.
The Denver Broncos started the season 6-0 while Von Miller served a suspension. Could they win a Super Bowl without him in the lineup as well?
The answer to that question could be forthcoming. Miller left Sunday's win over the Texans, and the Denver Post's Mike Klis reported that "there is fear" among the Broncos that Miller suffered a season-ending ACL injury. Miller will undergo an MRI Monday.
As with Jake Long's knee injury Sunday, Miller's appeared to occur without any real contact to his leg. Miller was trying to fight off a block when his leg buckled. Nate Irving replaced him in the lineup after he left and presumably would inherit Miller's starting spot should the injury be a long-term one.
Miller missed the Broncos' first six games after violating the league's drug policy. He returned just in time for Denver's first loss of the season, at Indianapolis.

Denver clinched the AFC West and a first-round bye Sunday with its win and Kansas City's loss. It will have a shot to lock up the conference's overall No. 1 seed next week, with either a victory over Oakland or a New England loss.
