What It Means:

After a fracture was ruled out, a high-ankle sprain became the most likely diagnosis, and it essentially guarantees Johnson will miss multiple games. The Rams supported that notion by claiming cornerback Dwayne Gratz off waivers. E.J. Gaines and Troy Hill will see more play in the meantime, but replacing Johnson will be a tall task for the Rams secondary.

Johnson has tallied 22 tackles, with nine deflected passes, one interception and one recovered fumble through five games this season. He's been one of the best corners in the NFL so far in 2016, helping the Rams to a ninth-overall ranking in Adjusted Defensive Passing Net Expected Points allowed per play.
