The Lions have chosen to hold the door open to their free agent defensive tackles, and today, another is walking in.

According to Jim Thomas of the St. Louis Post Dispatch, former Rams defensive tackle Kendall Langford is visiting the Lions today.

The Lions have chosen to not use the franchise tag on Ndamukong Suh (which would have hit them for $27 million for one season).

And a year ago, they elected not to pick up the option year on defensive tackle Nick Fairley, which makes him a free agent next week as well.

The Lions can continue to negotiate with both Suh and Fairley, but bringing in Langord’s also a tacit realization that they might be needing to backfill the position soon.
