Arizona Cardinals running back David Johnson suffered an apparent wrist injury during the second half of the team's game versus the Detroit Lions. He took a bit hit to the wrist on a fourth quarter carry but stayed in the game and subsequently fumbled on his next carry. An update is expected shortly but fear of a break here is what should be on the minds of his fantasy football owners. The clear number 1 pick in all fantasy football drafts this summer, an injury here surely is as big as it gets. Stay tuned.
