Garrett (knee) did not participate in Monday's training camp practice, Stu Jackson of the Rams' official site reports.
Garrett has been held out of practice for the last couple of weeks while recovering from swelling in his knee. He's unlikely to play in Thursday's preseason finale against the Chargers, but he still has time to progress enough in his recovery to be cleared to play Week 1 against the 49ers on Thursday, Sept. 10.
