Sun Devils coach Todd Graham announced at the start of spring practice Monday that Durant was suspended for violation of team rules but didn't get into specifics.
However, a Tempe police report shows the linebacker was arrested March 7 on allegations of domestic violence and aggravated assault.
Police say Durant's girlfriend accused him of hitting her in the face and grabbing her around the neck.
Durant is scheduled for a preliminary court hearing Wednesday.
He enrolled early to participate in the Sun Devils' spring practice, but wasn't listed on the roster handed out by the school Monday.
