Injuries — mostly minor — are catching up to the Lions in their fifth day of training camp.
 Tight end Casey Fitzsimmons will be out longer than first expected with a an ankle sprain that coach Jim Schwartz described as “not a high ankle (sprain), but it has some components.’’ Fitzsimmons is wearing an orthopedic boot on his injured left foot. His return will be determined on how it quickly responds to treatment. He  injured the ankle on Sunday.
Cornerback Keith Smith sat out practice with a groin injury. He will be out a little longer than day to day.
 Schwartz said the rest of the injured are on day-to-day status.
 That includes rookie safety Louis Delmas who missed his first practice this  morning with a sore left knee. He had it tested this morning as a precaution and the results were not in at noon. Delmas said he didn’t injure it on a specific play on Tuesday, but it started swelling up during team meetings Tuesday afternoon. Delmas said there’s no history of injury with that knee.
 Safety Daniel Bullocks was out with some knee soreness.
 Rookie tight end Brandon Pettigrew remains day to day with a thigh issue.
