After resting his sore foot Wednesday, Bears Pro Bowl defensive end Julius Peppers returned to practice Thursday at Halas Hall.
Peppers has had a strong start to the season with two sacks.
Bears linebacker Brian Urlacher was held out by Bears coach Lovie Smith, who indicated that a practice off may become the "routine" moving forward. Urlacher had a knee scope in early August but has played in both games.
He was pulled early in the opener but played the entire game against the Green Bay Packers.
Bears running back Matt Forte did not practice again after suffering an ankle injury against the Packers.
For the Rams, defensive tackles Michael Brockers and Matt Conrath, safety Matt Daniels, running back Steven Jackson, fullback Brit Miller and tackle Rodger Saffold didn't practice.
Offensive tackle Wayne Hunter was limited.
