ALLEN PARK -- Middle linebacker DeAndre Levy, who missed the first two regular season games with a groin injury, could play Sunday at Minnesota.

Injuries have prevented the Lions from playing all 11 of their defensive starters at the same time, but defensive coordinator Gunther Cunningham said that tide seems to be turning.

“(Louis) Delmas is practicing more than he ever has, Levy stepped up and practiced for two straight days,’’ Cunningham said today (Thursday). “I’m going to take him home with me, he’s not going anywhere. Hopefully we have our middle linebacker back.’’

Landon Johnson filled in for Levy the first two games, but this week Johnson will likely play on the outside in place of Zack Follett who is out with a concussion.

Delmas has been dealing with a groin injury since the end of June. But he said when he’s on the field he is 100 percent. This week’s injury report lists Delmas as having groin, bicep and calf injuries.

Also, right guard Stephen Peterman who has not practiced this week, hopes to practice on Friday and play on Sunday.

What kind of injury is it? “Whatever Jim (Schwartz) says it is,’’ Peterman said with a smile. He’s listed on the injury report with a foot injury.
