ALLEN PARK -- Tight end Brandon Pettigrew, who missed the first day of practice, was back at it today (Sunday). Pettigrew is one of three Lions coming off ACL surgery and the plan is to let those three get adjusted slowly. During two-a-days they will only participate in one of the sessions. And coach Jim Schwartz said they will also get one day off each week.

Pettigrew participated during OTAs and minicamp so it was somewhat of a surprise when he wasn't on the field on Saturday.

Running back Kevin Smith is another ACL survivor and he has practiced both days so far and looked solid.

Cornerback Jack Williams, the third of the ACL rehabbers, hasn’t practiced the first two days.

Safety Louis Delmas, who missed Saturday’s practice to attend a funeral, was back today, but he will remain on the physically unable to perform list until he gets back in condition following a groin injury during minicamp six weeks ago.

Defensive end Jared DeVries and Will Heller each have small lingering injuries and Schwartz said he expects them to practice soon.
