Kyle Hamilton (knee) returned to practice on a limited basis Thursday, mostly observing, during the portion open to the media.
Hamilton said after practice that he was still not sure if he would play in Sunday's pivotal game against the Miami Dolphins.
"Day by day," Hamilton said. "It's a short week, I have a day less to kind of evaluate everything. I'll do everything I can to make it to the game."
The versatile starting safety left the game in the fourth quarter of Monday night's 33-19 victory over the 49ers, a game in which Hamilton had two interceptions and earned AFC Defensive Player of the Week.
Hamilton said he re-aggravated the knee injury he suffered Dec. 10 against the Rams but was thankful the injury wasn't more serious.
"I was talking about taking the brace off before the game," Hamilton said. "It was annoying me. Something told me not to and I'm glad I didn't. I don't know, the brace might have prevented something else from happening. I got my ankle rolled up on and I guess it kind of rolled up into my knee, caused some knee pain."
Wide receiver Zay Flowers (calf), who leads the team with 74 catches for 752 yards, did not practice. Neither Flowers nor Hamilton have missed a game this season.
Starting cornerback Brandon Stephens (ankle), cornerback Jalyn Armour-Davis (concussion) and linebacker Del'Shawn Phillips (shoulder) did not practice.
Starting right guard Kevin Zeitler (knee/quad), who did not participate in Wednesday's walkthrough, practiced Thursday on a limited basis. Cornerback Arthur Maulet (knee), offensive lineman Patrick Mekari (concussion) and punter Jordan Stout (back) were also limited.
Defensive tackle Broderick Washington (elbow) was limited Wednesday, but was a full participant on Thursday.
For the Dolphins, numerous players are dealing with injuries. Two explosive playmakers missed practice for the second straight day – running back Raheem Mostert (knee/ankle), who leads the league with 18 rushing touchdowns, and wide receiver Jaylen Waddle (ankle).
All five starting offensive linemen were limited – left tackle Terron Armstead (knee/ankle/back), left guard Lester Cotton (hip), center Liam Eichenberg (calf/ankle), right guard Robert Hunt (hamstring) and right tackle Austin Jackson (oblique).
Starting quarterback Tua Tagovailoa (left throwing thumb), starting outside linebacker Andrew Van Ginkel (wrist), starting cornerback Xavien Howard (hip/thumb), starting safety Javon Holland (knees) and reserve wide receiver Robbie Chosen (concussion) were also limited.
