The Detroit Lions released their Week 4 initial injury report and two starters missed practice, while three starters returned.

The Detroit Lions and Seattle Seahawks will face off on “Monday Night Football” in Week 4, and with that privilege comes a slight alteration to the teams’ weekly schedules. Instead of releasing an injury report on Wednesday, Thursday, and Friday, things get pushed back a day, meaning the first official injury report will be out on Thursday, followed by a second on Friday, and injury designations will be made on Saturday.

The Lions have a lot of injuries to sort through this week, so let’s take a look at Thursday’s injury report and get you up to date with what we know. Of note, any changes from last week’s report will be bolded.

In one fell swoop, the Lions lost both their primary edge rushers splitting starting reps opposite Aidan Hutchinson. In base sets, the Lions deployed Derrick Barnes in the SAM linebacker role, while leaning on Marcus Davenport in both base and subpackages.

The severity of Barnes’ knee injury is still unknown, meaning it’s not entirely clear how long he will be out beyond the mandated four games, while Davenport’s injury is believed to be season-ending.

In both situations, the Lions will be looking for replacements. Josh Paschal has the closest skill set to Davenport and seems the most likely to step into his role, but the Lions may supplement some situational role to other players like Levi Onwuzurike and James Houston. Unfortunately, there’s not as clear a replacement for Barnes, which will likely result in a replacement by linebacker committee.

On Thursday morning, coach Dan Campbell informed the media that they don’t plan on playing Ragnow this week, instead giving him this week plus next week’s bye to heal up and reassess.

“We’re going to put Frank down this week,” Campbell said. “So I’ll go ahead and get that out of the way. We can go round and round if we want, we’re not even going to mess with that. Look, Frank’s tough. He’s just tough as nails. If anybody can play through it, it’s him. I think we have to be smart. It’s early in the year, we have a lot of football left.

LaPorta tried to play through his ankle injury multiple times last Sunday but struggled to do so. Fortunately, it was reported that his ankle sprain is considered “low” which means he could still be in the mix to play this week. Obviously, not practicing is not a great initial sign, but he was working with a trainer and he’ll have two more practices to test things out.

Skipper was injured early in the Cardinals game but was able to return to game action. It’s possible his injury is lingering, or that the Lions are giving him an early week break to get an extra day of rest, like they did with Graham Glasgow last week.

Melifonwu continues to not practice which has to be both frustrating and aggravating for everyone involved. At this point, it’ll be hard for him to recover and acclimate in time to get any meaningful snaps until after the bye.

McNeill injured his shoulder in the first half of Week 3 and was unable to return. The good news is that he returned to practice this week, which is a big step in the right direction toward playing.

“Alim’s doing better, he’s day-to-day,” Campbell said ahead of practice. “He’ll be out there running around today, so we’re pretty good there.”
