ALLEN PARK — The Detroit Lions will be without safety Kerby Joseph again this weekend, while listing seven other players as questionable.

Joseph and fellow safety Brian Branch were the only players ruled out ahead of Sunday’s game against the Los Angeles Rams. Branch is out for the season due to an Achilles injury, but has not been placed on injured reserve yet. And Joseph, who will now miss his eighth straight game, suffered a setback and could be a candidate for injured reserve, per Dan Campbell.

The Lions listed tight end Shane Zylstra (knee), running back Sione Vaki (thumb), wide receiver Kalif Raymond (ankle), guard Christian Mahogany (fibula), safety Thomas Harper (concussion protocol), left tackle Taylor Decker (shoulder/rest) and guard Kayode Awosika (foot) as questionable.

Decker has not practiced this week. But he’s been dealing with a shoulder injury all season and is coming off playing three games in less than two weeks. Awosika missed last week’s game against the Dallas Cowboys due to his foot injury. The veteran guard has practiced in a limited capacity all week long.

Trystan Colon and Miles Frazier split duties at left guard last week for Awosika. The Lions will have a decision to make there between those three options, but perhaps for only another weekend.

Mahogany returned to practice this week. He seems like a longshot to play this weekend based on his injury. But the Lions are listing him as questionable after logging three limited practices in his first action back on the field.

Zylstra has been back at practice for two weeks in his return from injured reserve. Heading into the weekend, the Lions have only one tight end on their 53-man roster (Anthony Firkser) and hope to get Zylstra back.

Campbell said Harper has a chance to play against the Rams despite spending the week in concussion protocol. The Lions could sure use Harper, with Branch and Joseph both out, to hold things down at safety with Avonte Maddox against the high-powered Rams.

“Harper will be out there at practice today, so feel pretty good about him, but we’ll see,” Campbell said on Friday morning. “There again, I can’t give you definitives right now, but that’s kind of where we’re at.

“So, we’ll be good. Look, (Erick) Hallett’s been taking reps, (Daniel Thomas) DT’s been taking reps, Maddox has been taking reps. We’ve got plenty of guys. They’re getting valuable reps, so we’re good.”

Raymond has missed two consecutive games due to an ankle injury suffered against the New York Giants. He has a shot to return after working back into practice, and should reclaim his role returning punts.

Vaki has continued to play through his thumb injury. He hasn’t returned kickoffs since suffering the injury, with Tom Kennedy and Jacob Saylors taking over.
