The Detroit Lions continue to work their way through the bumps and bruises that occur during the physical part of training camp. On Monday, the Lions added another three players to their injury collective, and on Wednesday morning, coach Dan Campbell provided updates on their timelines for returning to practice.

Detroit Lions general manager Brad Holmes and his staff have gained a reputation for finding hidden gems in the mid to late round of the NFL draft, and this year's draft brought with it another potential steal in former Georgia safety Dan Jackson.

Rookie safety Dan Jackson, the Lions' seventh-round draft pick, is out indefinitely after injuring his shoulder in Sunday's practice.
