The news is not what we wanted to hear, but there is also no confirmation from the team, but Ian Rapoport of NFL.com tweeted this out minutes ago:
Sources: #AZCardinals RB David Johnson (wrist) is expected to miss an extended period of time. Getting more opinions, but an IR candidate.

This is devastating news for the Cardinals and their fans, but we will wait for confirmation from the team.
If David Johnson goes on injured reserve, the Cardinals would not get their All Pro running back back until after week nine of the season.
