Cardinals running back David Johnson only suffered an MCL sprain in the regular season finale, coach Bruce Arians says (Twitter link via Cardinals PR man Mark Dalton). That means no surgery for the Cardinals star, only rehab and rest.

The Cardinals are thrilled to learn that Johnson will not have to go under the knife after suffering a gruesome-looking injury in Week 17. An MCL sprain is no walk in the park, but a more serious knee injury such as an ACL tear could have sidelined Johnson for a good chunk of next season.

Johnson, 25, ran for more than 2,000 yards from scrimmage while scoring 20 total touchdowns. While this was a down year for the 7-8-1 Cardinals, Johnson had a tremendous individual season and asserted himself as one of the very best running backs in the NFL.

In other Cardinals news, three teams in search of a head coach have asked to speak with offensive coordinator Harold Goodwin. Also, the draft order is set for the top 20 and Arizona holds the No. 13 overall pick.
