Dolphins edge rusher Jaelan Phillips injured his back during Friday’s practice.
He is listed as a limited participant, and the Dolphins gave him a questionable designation.
Phillips had a career-high 11 tackles in the season opener as well as half a sack and two quarterback hits.
He has never missed a game, playing all 35 games since the Dolphins made him a first-round pick in 2021.
The Dolphins also list left tackle Terron Armstead (back/ankle/knee), defensive back Elijah Campbell (knee) and tight end Julian Hill (ankle) as questionable. All three were limited in all three practices.
