[Chiefs Blog] Chiefs inside linebacker Derrick Johnson, coming off perhaps the most productive two-game stretch of his five-year career, said Thursday that he has an injured groin and will not play Sunday at Philadelphia.

“Bad timing,” he said.

Indeed. As the Chiefs prepare to face the Eagles’ high-scoring and multi-dimensional offense, which is almost definitely to include the Wildcat formation, Kansas City needs as many playmakers on defense as possible. Demorrio Williams is expected to start alongside Corey Mays at the other inside position.
