The Jaguars issued the first of three injury reports for the week Thursday, with Walker and linebacker Yasir Abdullah the only players listed as not participating. Abdullah missed Sunday with a hamstring injury.
Brown practiced limited on Thursday after missing Sunday with a shoulder injury.
Jaguars players practicing limited Thursday: Rookie running back Bhayshul Tuten (shoulder), Brown, starting left guard Ezra Cleveland (concussion/ankle), offensive lineman Chuma Edoga (knee), starting right Anton Harrison (elbow), starting right guard Patrick Mekari (knee), rookie reserve offensive lineman Wyatt Milum (knee) and starting Eric Murray (neck).
"We'll see in terms of getting those guys back," Coen said. "We have to be smart with them this week in terms of practicing, getting them the mental reps, also looking at how many reps they can take – just being smart about that."
Coen cited the experience of reserve linemen such as Chuma Edoga and Cole Van Lanen Thursday as "super-valuable" considering the injuries along the line.
"It's great to be able to have the ability to mix and match if you need to, and we did so much of that from the spring through training camp," Coen said. "That has now allowed it to be a little bit more seamless in season."
