It's another injury for another player in the Cardinals backfield.
This time, it's new addition Chris Johnson, was signed to the club last week.
Johnson did not suit up in the team's game vs. San Diego on Sunday due to a pulled hamstring he suffered in Thursday's practice, per Bruce Arians.
The coach is now calling him "day-to-day" after it was believe he would be out 1-2 weeks.
Though the club will be without Johnson, rookie David Johnson put on a solid performance with 13 carries for 66 yards.
The back out of Northern Iowa had also been battling a hamstring injury before returning to practice last week.
