ALLEN PARK -- Louis Delmas was back at practice Thursday morning after sitting out on Wednesday. If all goes well, Delmas will play a few series in Saturday’s home preseason game against Cleveland.

Delmas, the starting free safety, injured his groin in the late June minicamp and had not been back to 100 percent.

Defensive end Jared DeVries was nowhere in site for the start of Thursday’s practice. There could be an update from coach Jim Schwartz around lunchtime. DeVries went to see an out-of-town specialist for a second opinion on his knee which has been an issue since the start of training camp.

Also on Thursday, DE Sammie Hill did not practice and neither did safety C.C. Brown. The other injured players sitting out were DE Lawrence Jackson, S David Roach, CB Aaron Berry, K Jason Hanson and CB Jack Williams.
