For the Denver Broncos, things are simply getting worse.

The team is 0-4 and blew a 14-point lead Sunday to the Jacksonville Jaguars at home, eventually losing 26-24. But that might have even the worst part of the day.

Outside linebacker Bradley Chubb partially tore his anterior cruciate ligament in the loss and will miss the rest of the 2019 season after undergoing surgery, coach Vic Fangio confirmed Monday.

Chubb actually returned to the game after appearing to suffer his injury in the third quarter. He had picked up his first sack of the season earlier in the game.

“Well, he did have cramps, that was separate,” Fangio said. “And then he hurt his knee at some point in the game, but he felt good enough to come back in. And, actually, he played that last series pretty damn well. He had some pass rushes, caused that fumble that we weren’t able to get. So he was surprised as anybody, I think, this morning when he woke up feeling the way he did.”

Chubb, 23, is one of Denver’s top pass rushers alongside linebacker Von Miller. Taken with the No. 5 overall selection in the 2018 draft, he recorded 12 sacks as a rookie.

“It’s a huge loss,” Fangio said. “He’s one of our better players, obviously. He’s a tempo-setter. Great player, great person, leader, all that. So it is a loss.”

The Broncos hired former Chicago Bears defensive coordinator Vic Fangio to be their head coach this offseason, but the results haven’t instantly translated on the field. Denver failed to generate a sack and failed to generate a turnover in its first three games.

Against the Jaguars, the Broncos did register five sacks, but they still have not forced a turnover.

With Chubb out, rookie linebackers Justin Hollins and Malik Reed are the next options on the depth chart. Fangio said it “would probably be more of a committee thing” in terms of how the Broncos approach Chubb’s replacement.
