Five don't walk through for Lions Monday

ALLEN PARK, Mich. -- Five players, including wide receiver Calvin Johnson, did not practice during the Detroit Lions' walkthrough Monday during its short week preparation for Green Bay on Thursday.

Johnson (knee), safety Glover Quin (ankle), safety Louis Delmas (knee), defensive end Israel Idonije (knee) and cornerback Chris Houston (foot) all sat out the walkthrough.

The biggest concern on the list is Houston, who left Sunday's 24-21 loss to Tampa Bay with the foot injury and did not return.

When asked about Houston's availability for Thursday, Schwartz said the Lions will have to "wait and see."

If Houston can't play, Detroit would likely go with rookie Darius Slay in his place, opposite veteran corner Rashean Mathis.
