The Lions are the only team today with transactions that aren’t just standard gameday practice squad elevations. In addition to the normal gameday transactions, Detroit also placed starting cornerback Jerry Jacobs and backup tight end James Mitchell on injured reserve before their first home playoff game in 30 years. 
Jacobs is certainly the bigger loss of the two. The third-year cornerback out of Arkansas has continued to extend his role in each year, starting 12 games on the Lions’ defense this year. In 15 games this season, Jacobs is tied for second on the team for interceptions (3) and tied for third on the team for passes defensed (8). Jacobs had started the first 12 games he had appeared in this year but was forced to take a bit of a back seat in recent weeks.
With Jacobs in a limited role the past few weeks, Kindle Vildor has been starting opposite usual starter Cameron Sutton, with big contributions coming from second-round rookie Brian Branch and Khalil Dorsey. That plan is expected to continue as Jacobs becomes officially unavailable, though Sutton and Branch are dealing with a few injury issues themselves.
Mitchell was expected to play a bigger role in the offense if starter Sam LaPorta was unable to play after last week’s injury. Luckily, LaPorta seems to have avoided disaster and currently only holds a questionable status heading into tomorrow, so there’s a good chance he will be good to go, lessening the impact of Mitchell’s absence. Brock Wright will continue performing as TE2.
After losing a cornerback and tight end to IR, the Lions promoted a cornerback and tight end from the practice squad, signing Anthony Firkser and Chase Lucas to the active roster. Firkser and Lucas will be able to provide some depth at tight end and cornerback, respectively, as injuries threaten to impact Detroit’s postseason aspirations.
Lastly, the Lions announced their standard gameday practice squad elevations for tomorrow, as well. Joining Firkser and Lucas will be defensive lineman Tyson Alualu and fullback Jason Cabinda.
