Cardinals coach, players shocked by arrest of running back Dwyer

Arizona Cardinals coach Bruce Arians says domestic violence is a worldwide problem and should be addressed everywhere, not just in the NFL.

He says that if the current so-called "scar" on the NFL leads to more awareness of the problem, then it's, in his words, "damn good."

Arians spoke to a mob of reporters after practice on Thursday, a day after running back Jonathan Dwyer was taken into custody at the Cardinals' practice facility on domestic violence charges.

Arians says Dwyer expressed shock at the arrest and insisted he was innocent.

Arians says if Dwyer is found guilty, he is finished with the Cardinals. If he's exonerated, then the team would welcome him back.

The Cardinals placed Dwyer on the reserve/non-football illness list, meaning he can't play for the team again this season.
