Practice report: Lions down corners

ALLEN PARK, Mich. -- Things are not looking promising for Detroit when it comes to having healthy cornerbacks.

Both Chris Houston (toe) and Darius Slay (knee) did not practice for the third straight day, and while it is highly doubtful Slay plays as he recovers from a torn meniscus, Houston's availability becomes a major concern for the Lions against Baltimore.

If neither one plays, Detroit will likely look to Jonte Green, who has played sparingly, or Chris Greenwood, who was promoted from the practice squad last week, to play in Houston's place.

Bill Bentley would be another option. But Detroit uses him in the nickel, so it would be between him and Don Carey there.

Also not at practice was safety Louis Delmas (knee), but this is his typical maintenance day.
