Detroit Lions safety Louis Delmas' stats aren't of the "wow" variety.

His numbers, as average as they seem, don't really explain what he does for the Lions secondary. He's a ballhawk, a player who just disrupts the rhythm of opposing receivers. He had five pass deflections in 2011, along with 51 tackles (36 assists). He brings energy that can't be quantified in the box score, and he could bring that energy as soon as the Lions' first regular-season game, according to a report.

The 5-foot-11, 202-pound fourth-year NFLer out of Western Michigan underwent successful "clean-up surgery" in his left knee. That bodes well for a secondary that has its share of question marks surrounding it.

With any luck, he'll be ready to go for the Lions' season-opener Sept. 9 against the visiting St. Louis Rams at Ford Field in Detroit.

On Wednesday, the team announced Delmas had undergone surgery on his left knee. The  procedure was performed by renowned orthopedic surgeon Dr. James Andrews. 

Following Wednesday's practice, Lions coach Jim Schwartz labeled the recovery process week-to-week.

"As soon as he is able to get out and go and keep it from getting sore, then he'll be back," Schwartz said. "The reason he ended up getting it done was an effort to be able to get back on the field."

Delmas had already missed the majority of training camp because of the knee.  He tried to return last week, but left the field after working just a few snaps of seven-on-seven drills.

"At first it was sore, and then it was like, 'Okay (OK), take a day off'," Schwartz said. "The next day it was still sore. Then he tried to go again. He tried to get back in, and we just weren't getting anywhere with it."
