Allen Park Ė The last thing the Lions want is to face the Packers and quarterback Aaron Rodgers without their best cornerback. But it could happen.
Starting left cornerback Chris Houston, who injured his leg in the second half Sunday against the Bears, was not on the practice field Wednesday during the portion open to the media. Coach Jim Schwartz has been more guarded about Houston's status than he normally about injuries.
"He has a leg injury," Schwartz said on Monday. "Iíll just keep it at that and we will just see where he can get to this week and try to get him back as quick as we can. If he canít go then we will have next guy up. I mean thatís what we do in this league."
He added that he didn't think it was more than a "day-to-day, week-to-week" injury.
Starting right cornerback Rashean Mathis, who missed most of the game Sunday after taking a shot to the head, was back at practice Wednesday. If Houston is unable to play Sunday, Mathis would most likely play left corner.
Rookie Darius Slay would start at right corner.
Receiver Patrick Edwards, who has missed the last two games with a high ankle sprain, was also back at practice.
Missing practice were safeties Louis Delmas (knee) and Glover Quin (unspecified) and receiver Calvin Johnson (knee).
The complete injury report will be released at 4 p.m.
