Jermar Jefferson has been with the Lions since being drafted in 2021 but has struggled to find playing time, having not appeared in a game since 2022. Despite being cut at the end of training camp for three consecutive years, he has remained with the organization, demonstrating resilience and a positive mindset as he seeks opportunities to contribute, especially now with increased competition for carries in the absence of Montgomery.

Jermar Jefferson, a running back on the Lions' practice squad, was featured in a social media post that raised concerns about revealing the team's playbook. In the post, he was seen posing or dancing, with a whiteboard in the background displaying offensive play calls and protections. This incident caught the attention of head coach Dan Campbell, who expressed surprise and indicated the need to address the situation.

Jermar Jefferson was waived by the Lions as part of their roster cutdowns.
