The will be without several key players when the team takes the field this Sunday against the Seattle Seahawks.It appears that safety is the frontrunner to start at safety to replace Tracy Walker, who is now out for the season with a torn Achilles. and Kerby Joseph are also candidates to see playing time this weekend.But, the team is still evaluating and deciding who is the best option to play alongside veteran DeShon Elliott.Yeah, well, I would say we gave all three of those guys reps this week, and todays still part of the proce s," Campbell said. "And so, I think were going to go with the guy who gives us the best chance and go from there. But, I dont nece sarily see playing by committee right now. Were just going to take this as it comes, and after today, well kind of make a decision on who we see and then move from there.On Friday, wideout DJ Chark returned to practice, after sitting on Thursday.Chark is dealing with an ankle injury, and is listed as questionable ahead of the Seahawks game.Detroit Lions' Friday Injury ReportOut -- Ankle/shoulder (NP)WR Amon-Ra St. Brown -- Ankle (NP)OL Jonah Jackson -- Finger (NP)DL John Cominsky -- Wrist (NP)K Austin Seibert -- Right groin (NP) QuestionableDJ Chark -- Ankle (LP)WR Josh Reynolds -- Ankle (LP)No designation -- Foot (FP)OL Frank Ragnow -- Foot (FP)LB Chris Board -- Knee (FP)CB Bobby Price -- Shin (FP)
