David Johnson took a huge hit during Sunday’s loss to the Detroit Lions, but it sounds like the Arizona Cardinals star avoided a significant injury.
Ian Rapoport of NFL Media is reporting that an MRI for Johnson revealed a sprained wrist. As Rapoport notes, that could be the reason Johnson fumbled the first time he carried the ball after getting hurt.
The preliminary diagnosis for #AZCardinals RB David Johnson is a sprained wrist, sources say. No break. MRI tomorrow. Next play, he fumbled.

Johnson caught a pass inside the 5-yard line for a first down on 2nd-and-20, and he was slow to get up after taking a big shot from a defender. He walked off under his own power but was later listed as questionable to return following his fumble.
The good news is obviously that Johnson did not break any bones. Depending on how quickly he recovers, he could be available for Week 2.
