The interview comes after the 49ers parted ways with special teams coordinator Brian Schneider, who had been a member of head coach Kyle Shanahan's staff since 2022.
Modkins has been with the Lions since 2021, working under special teams coordinator Dave Fipp. He also has a personal connection to the 49ers, as his father, Curtis Modkins, served as the team's offensive coordinator in 2016. The interview was reportedly conducted virtually.
