DENVER -- The initial belief is that Green Bay Packers star pass rusher Micah Parsons suffered a torn ACL in his left knee, a source confirmed to ESPN.

The news was first reported by Pro Football Talk.

Parsons sustained a noncontact injury to his left knee in the third quarter against the Denver Broncos .

In the same quarter, the Packers also lost perhaps their most explosive offensive player in Christian Watson to a chest injury.

Parsons pulled up while trying to rush Broncos quarterback Bo Nix and immediately grabbed his left knee. He was able to walk to the locker room but with a significant limp. He was ruled out in the fourth quarter.

Parsons did not record a sack Sunday, but he made his presence felt early when he forced a fumble against Broncos running back RJ Harvey
