All offseason, there has been talk from the Cardinals -- and coach Bruce Arians -- of not overworking Carson Palmer's arm. The quarterback didn't throw during team work during OTAs until the last couple, and then minicamp. The idea was to keep him fresher for the season. Whether that improved his arm strength, well, David Johnson has a story.

Johnson went to the San Diego area after minicamp had ended, to take part in Palmer's annual work near Palmer's California home.Palmer was zinging passes to Johnson one day.

"He was throwing some heat and his arm was so fresh, I had to get stitches in my finger," the running back said.

A throw had cut Johnson's pinky. He wasn't sure what it was, whether the laces caught him wrong or the leather simply sliced him, but Johnson said he actually suffered a subluxation of the finger. Still, he kept playing catch and didn't get it looked at until later.

"He's still got it," Johnson said. "To say the least, he definitely still has an arm."

UPDATE: Palmer said he felt bad about hurting Johnson but "he wasn't wearing gloves, so I can put a little bit of the blame on him." That wasn't the only reason Palmer felt bad. "We washed it with the hose, and I thought 'That's probably not the cleanest water in Southern California' "
