For the second-straight season, a Lions defensive coordinator could be on the move. According to NFL Network’s Ian Rapoport , the Dolphins have requested permission to interview Lions DC Kelvin Sheppard for their head coaching vacancy.

Sheppard doesn’t come with as much fanfare nor experience as Aaron Glenn did last offseason. The former third-round pick joined Detroit’s coaching staff as an OLBs coach in 2021, and he shifted to linebackers coach in 2022. He held that role for three seasons before earning the promotion to defensive coordinator ahead of the 2025 campaign.

Detroit’s defense took a step back with Sheppard at the helm, as the team’s points-per-game mark jumped from 20.1 in 2024 to 24.3 in 2025. This led some to speculate that the 38-year-old may not even retain his current role in 2026. However, coach Dan Campbell was quick to endorse his coordinator, noting that Sheppard has grown into the job throughout the year.

Further, Sheppard has a bit of an excuse thanks to the number of injuries on Detroit’s defense. Star safeties Brian Branch and Kerby Joseph plus cornerbacks D.J. Reed , Terrion Arnold , and Ennis Rakestraw all spent time on injured reserve, with several of those players unavailable for the stretch run of the season. While injuries are only part of the reason for the Lions’ defensive regression, they seemingly also helped Sheppard maintain his reputation.

Now, he’ll have a chance to take the next step of his career in Miami. Sheppard actually had the most productive season of his playing career with the Dolphins in 2015, and he may be tasked with turning around a franchise that’s looking to return to their winning ways. The Dolphins currently have one of the shortest list of head coaching candidates in the league, although more names will surely be added over the next few days. The team’s current list of definitive and rumored targets includes:
