ALLEN PARK — Middle linebacker Ernie Sims suffered a “fairly significant” shoulder injury diving out of bounds in Sunday’s loss to Minnesota. He is undergoing more testing. Coach Jim Schwartz said today that there’s a good chance he will miss some time. The coach would not be specific about who would replace him, but did say there’s a chance it could be rookie Deandre Levy, a third-round pick.

If Levy should start — and that’s still an if — he would be the fifth rookie starter on the team. Already on defense there are defensive tackle Sammie Hill and safety Louis Delmas who are both rookies. On offense there are two rookie starters —  quarterback Matthew Stafford and tight end Brandon Pettigrew.
