End of the Lions road for Corey Williams?

Depending on how you configure the Detroit Lions' defense, anywhere from half to three-quarters of their 11 starters are eligible for free agency after this season. There are plenty of decisions to be made, and you wonder if one hasn't already played out.

The Lions will place nose tackle Corey Williams on injured reserve this week, according to Dave Birkett of the Detroit Free Press. Williams has a knee injury that required surgery earlier this season and has limited him to seven games. He is one of the Lions' pending free agents, and given the emergence of second-year player Nick Fairley, you wonder if he would be an easy player for the Lions to move on from.

Williams, 32, is one of the more respected veterans in the Lions' locker room, but the Lions have enough depth at the position to move on without him. Former Lions defensive lineman Andre Fluellen reportedly will re-sign to fill Williams' roster spot.
