With the core of the team and coaching staff having been together for over three seasons, the Lions feel like they have the intelligence and maturity to handle a scaled-back practice on Wednesday. The benefits of a walkthrough allow the team an extra day to recover, and in turn, sets the team up to have more energized practices on Thursday and Friday. Despite the Lions' intense Thursday practice, they were fortunate to have every player on their active roster participating, including star tight end Sam LaPorta, who missed last week’s game with a shoulder injury. Let’s take a look at Thursday’s injury report and get you up to date with what we know. Note that any changes from yesterday’s report will be bolded. No practice None Limited practice CB Terrion Arnold (groin) — New injury Arnold appears to have suffered a midweek groin injury. Obviously it’s never good when an injury happens during the week of practice, but there are some promising signs. For one, he had a long media session in the locker room after practice, and he appeared to be in good spirits. We’ll know more about his status on Friday morning when coach Dan Campbell is expected to speak. Full practice TE Sam LaPorta (shoulder) TE Shane Zylstra (neck) CB Carlton Davis (thumb) CB Emmanuel Moseley (pec) — Days remaining in injury evaluation window: 5 LaPorta has been “trending the right way” and while he was only estimated to have been a full participant on Wednesday, this practice confirms he is on track to return to game action this week. Zylstra exited last Sunday’s game with a neck injury but with two full practices under his belt, the injury doesn’t seem overly concerning at this time. Davis played through his thumb injury last week and will likely be on the injury report until his thumb is fully healed. Practicing in full indicates he has not had any setbacks. Moseley is working through the final days of his injury evaluation window, and while the Lions can activate him at any time, they have until next Tuesday to make a decision. Removed from injury report Allen Robinson (concussion) Robinson was removed from the injury report as he has passed the necessary concussion protocols.
