Arizona Cardinals coach Bruce Arians told FOX Sports’ Alex Marvez and Bill Polian on SiriusXM NFL Radio that Johnson had to be taken out of practice after hitting his casted hand.
“There’s no telling what germs you’re trapping in there when you ball it up and put the cast on,” Arians said. “The stitches are still there. He could evidently lose more of the digit if he bangs it too much, and with any infection they could have to take more off. We’re going to be careful with it.”
