Chubb suffered the injury in Denver’s 26-24 loss Sunday to the Jacksonville Jaguars. He left the game twice — first for a calf injury, then for the knee injury — before returning to the lineup to close out the contest.
After the game, Broncos coach Vic Fangio said Chubb “had some calf issues and then I think he had another injury in his leg issue that he was able to come back from.”
Chubb spoke at his locker after the game and made no reference to his knee. The second-year linebacker has 20 tackles, one sack and one forced fumble this season for the winless Broncos (0-4).
