The good news is the MCL sprain will not require surgery. This was confirmed by the team's Twitter account:
BA says David Johnson has an MCL sprain and that Johnson will not require surgery.— Arizona Cardinals (@AZCardinals) January 2, 2017
Johnson also spoke to the media this morning. He said that he was never worried about his knee. He did say that he will miss the Pro Bowl later this month, as the injury will sideline him six to eight weeks.
In addition to his injury, Johnson spoke about his efforts to convince Larry Fitzgerald to postpone retirement. He talked about how given the fact that Fitz is a Hall of Fame receiver, he hopes he returns for next season. He mentioned that he's been actively trying to convince Fitz to come back.
So we've learned two things today: David Johnson is even godlier than originally thought, and the Cardinals just dodged a HUGE bullet. On the Red Zone Channel last night, Dr. Mark Adickes had predicted that this injury could potentially sideline Johnson for the start of the 2017 season. Obviously that isn't happening, so this is just a fantastic way to start the year.
Best of luck to Johnson as he recovers from this injury, and thank to you whoever is out there watching over this team. Happy Monday everyone.
