PHOENIX (AP) — Arizona Cardinals running back Jonathan Dwyer was arrested Wednesday on aggravated assault charges in connection with two altercations at his home in July involving a woman and an 18-month-old child, the latest in a string of such cases involving NFL players.

The Cardinals said they became aware of the situation on Wednesday and are cooperating with the investigation. Dwyer has been deactivated from all team activities. The NFL said the case will be reviewed under the league’s personal-conduct policy.

One of the counts was “aggravated assault causing a fracture” against the 27-year-old victim on July 21.

Panthers remove DE Greg Hardy from active roster: CHARLOTTE, N.C. (AP) — The Panthers announced they’ve placed Greg Hardy on the exempt-commissioner’s permission list, meaning the Pro Bowl defensive end has been removed from the team’s active roster until his domestic violence case is resolved.

The decision comes just hours after the Vikings took a similar disciplinary approach with Adrian Peterson, who is addressing child abuse charges in Texas.

Hardy was convicted July 15 of assault on a female and communicating threats after the victim claimed the 6-foot-4, 275-pound player threw her in the bathtub and onto a sofa covered with guns before threatening to kill her. Hardy is appealing the ruling and a jury trial is set for Nov. 17.

“We made a mistake,” Vikings owner Zygi Wilf said, “and we needed to get this right.”

Pegulas’ bid to buy Bills OK’d by NFL committee: ORCHARD PARK, N.Y. (AP) — Buffalo Sabres owners Terry and Kim’s Pegula’s bid to buy the Buffalo Bills for an NFL-record $1.4 billion was unanimously approved by the league’s finance committee.
