Arizona running back Ka’Deem Carey will face charges this week stemming from a domestic violence incident involving his pregnant ex-girlfriend on Dec. 23, according to reports.

Sgt. Chris Widmer, a spokesman for the Tucson Police Department, told multiple news outlets that charges will be filed this week.

The Arizona Daily Wildcat spoke with Carey’s girlfriend, Marissa Rambow over the phone. Although Rambow agreed to be identified, she refused to comment on “private matters between Ka’Deem” and her.

Carey’s lawyer has not yet returned a request for comment.

According to court documents pertaining to Rambow’s petition for an order of protection against Carey, which he received on Dec, 31, the incident occurred when he went into her room “to obtain a lighter to use illegal substance in home.”

Rambow, 23, asked him “multiple times” to leave the room and “he refused, pushed/shoved his way in and knocked [her] to the floor. Threatening [her] pregnancy and [herself].”

Carey then, according to the documents, slammed Rambow’s fingers in the door when she tried to prevent him from smoking the substance inside the house.

Rambow and Carey had been living together in the same home for the last year, she said.

Both UA head football coach Rich Rodriguez and athletic director Greg Byrne released statements on Sunday pertaining to the incident.

Rodriguez: “I’ve spoken with Ka’Deem and am aware of the case. We take these matters very seriously and will support the authorities however we can. Once more specific information is available, we will act accordingly.”

Byrne: “The University and Department of Athletics are fully aware of the situation. This is now a matter for the local authorities and we will fully cooperate and assist them as needed. At this point we will have no further comment.”

Carey was the nation’s leading rusher in 2012. The sophomore running back finished the season with 1,929 rushing yards and 23 touchdowns, both UA records.
