Starting defensive end Cliff Avril, who hasn’t practiced all week with a hamstring injury, is doubtful to play on Sunday. Schwartz rotates his defensive ends throughout the game so Avril’s presence would be missed.

“Regardless of whether you’re the starting end or the third end, you’re going to get time and you're going to roll through and all of those guys play. He’s done a little bit of stuff on the practice field this week. We’ll just see how he is on Sunday,’’ Schwartz said of Avril.  Jason Hunter is likely to start in Avril’s place.

Defensive lineman Turk McBride was claimed off waivers this week. Schwartz expects him to play at defensive end for the Lions, although he has played tackle also. The coach wouldn’t say if he plans to play McBride on Sunday.

Other injuries: DE Andre Fluellen (knee) and CB Eric King (shoulder) are listed as questionable for Sunday’s game. CB Phillip Buchanon (neck) DT Grady Jackson (knee), CB William James (foot) and G Daniel Loper (knee) were limited in Friday’s practice, but are probable for Sunday. Buchanon missed the opener at New Orleans.
