The Rams have placed safety Lamarcus Joyner on the non-football injury list.
Los Angeles had its annual conditioning test before the start of training camp on Wednesday.
Joyner will be eligible to come off NFI and practice whenever he is medically cleared.
Entering his fifth NFL season, Joyner has three career interceptions, 4.0 sacks, and two forced fumbles. Los Angeles moved him from slot corner to safety in 2017 — Joyner's first season under defensive coordinator Wade Phillips.
