An already bad season is turning ugly in Denver.
Pass-rusher Bradley Chubb tore his ACL and is out for the season, NFL Network's James Palmer reported.
ESPN first reported the news.
"He's got a partial tear of the ACL and will be out for the season," coach Vic Fangio later confirmed to reporters.
It's a brutal blow for the Broncos who started the season with four straight close losses.
Chubb had his best game of the season Sunday in the 26-24 defeat to the Jacksonville Jaguars. The young pass rusher gobbled up seven tackles, one sack, three QB hits and one tackle for loss. It was his first game with a sack this season.
Chubb exited the game briefly but returned to the tilt. Monday brought the devastating news that the season is over for the 23-year-old.
"He was surprised as anyone this morning when he felt the way he did," Fangio said.
Coming off a 12-sack rookie campaign, the Broncos expected a major leap from their edge rusher, who would see beneficial blocking situations opposite Von Miller in Fangio's system.
Things are going from bad to worse for John Elway's club.
