Teams had two weeks to place the franchise tag on one pending free agent, and five used it. Read more about how the tag works here.
Rams tag S Lamarcus Joyner

Lions franchise DE Ezekiel Ansah
The Lions designated Ansah as their franchise player for 2018. When healthy, the defensive end is worth all $17.143 million he'll earn with the tag. But would a long-term deal make sense for the Lions? Read more from Michael Rothstein.
