Not only did the Denver Broncos suffer their second walk-off loss of the season on Sunday but they also lost one of their star defensive players as well.

Outside linebacker Bradley Chubb left the game in the fourth quarter after suffering a knee injury. Yet, he was able to return to action and finish the game.

The initial diagnosis revealed that he could play through it to finish the game. On Monday, further examination showed that he had suffered a slight tear in his ACL and he would require season-ending surgery.

Chubb had found his footing as a true partner to Von Miller and gave the Broncos two of the strongest pass rushers in the NFL.
