Aftermath of Broncos "tackle"

Texans' Derek Newton stumbled as Von Miller ran in his direction. His ankle slipped underneath and his leg twisted in such a way he had not one, but TWO air casts put on. Sounds like a rarity, I've never seen two air casts on one player... Have you? Here is the video of the "tackle" that caused Derek Newton so much harm. - https://www.youtube.com/edit?o=U&vide... Update: He tore BOTH patellar tendons and is out for the season.
