Roquan Smith was not at Ravens practice Wednesday after leaving Sunday's game with a hamstring injury.
Smith came off the field late in the third quarter against the Steelers and returned, but he left again early in the fourth quarter and was later ruled out.
Smith, the NFL's leader in tackles with 110, was having his best game of the season with a game-high 13 tackles. Malik Harrison replaced Smith next to Trenton Simpson.
Smith hasn't missed a game during his time as a Raven. He has an extra day to rehab with the Ravens facing the Los Angeles Chargers on "Monday Night Football."
Defensive lineman Travis Jones, cornerback Arthur Maulet (calf), and safety Sanoussi Kane (ankle) also weren't at Wednesday's practice.
Jones was questionable for Sunday's game with an ankle injury and went down against the Steelers, but he returned and finished the game. Kane hurt his ankle on special teams Sunday and did not return.
Maulet suffered a calf injury last week, and he was seen in the locker room in a walking boot. He was ruled out against the Steelers on Friday.
