ALLEN PARK — Rookie quarterback Matthew Stafford did not practice today. Coach Jim Schwartz would not be specific about Stafford’s knee injury or whether he would practice at all this week or if he play on Sunday. Stafford was on the practice field in his jersey and Tigers baseball cap. He was not on crutches and had a sleeve around his right knee.

Stafford did not talk to the media and neither did Daunte Culpepper who will start if Stafford cannot go. Stafford injured his right knee in the fourth quarter of Sunday’s loss at Chicago. On Monday after testing had been done, Schwartz said that Stafford is day to day.

Stafford, the top overall pick from Georgia, started the first four games and was 79 of 139 for 894 yards with three passing touchdowns and six interceptions. He has a quarterback rating of 65.5. He also rushed for a touchdown.

In a conference call this afternoon Pittsburgh Steelers linebacker LaMarr Woodley said he’s preparing to play against Stafford.  “I just believe he is (playing),’’ Woodley said when asked to explain.
