The Denver Broncos put Brandon Jones on IR on Monday with a pectoral injury. It's a major blow to an underrated player on that defense. Overall, though, Denver's defense is still one of the most talented units in the league.
Vance Joseph is the team's elite defensive coordinator, and his job going forward did get a bit harder with Jones now being out for at least four games. With the way IR works, Jones would have to also miss the team's first playoff game.
He could realistically come back in the Divisional Round or AFC Championship Game depending on how things shake out.
