St. Louis Rams defensive end Chris Long will not return to Sunday's game against the Green Bay Packers with a knee injury.
Long had to be helped off the field after a second-quarter play in which the Rams notched their second interception of Packers quarterback Aaron Rodgers.
The 30-year-old remains a key contributor on a dominant Rams defensive front. He returned from last year's season-ending injury to start in each of St. Louis' first four games, recording two sacks and 10 total tackles.
