Johnson (shoulder) wasn't listed on the Commanders' injury report Wednesday.
Johnson strained his rotator cuff after being slammed to the ground by Ravens tight end Mark Andrews during a joint practice session in training camp. He registered career highs in tackles (29) and pass deflections (nine) in 11 games last season and will provide key depth for a secondary headlined by Kendall Fuller, Emmanuel Forbes, Darrick Forrest and Kamren Curl.
