Lions safety Louis Delmas missed the first four games of the season with a left knee injury. He now has another one.
Per a league source, X-rays were negative but further testing (specifically, an MRI) will be conducted on Monday. The injury happened in the third quarter. Delmas was examined on the sideline and then taken to the locker room.
Per various reports on Twitter, coach Jim Schwartz declined to characterize the condition as a re-injury.
