ALLEN PARK — Louis Delmas underwent a surgical procedure on Tuesday on his left knee, the team announced this morning (Wednesday).

The surgery was performed by Dr. James Andrews of Birmingham, Ala., a pre-eminent orthopedic specialist.

Delmas has missed the majority of training camp with knee soreness. He underwent knee surgery in December on his right knee.

Obviously he won’t be ready for Friday’s preseason game.

The team offered no other information. Coach Jim Schwartz may have more to say on the Delmas situation following this morning’s practice.
