According to an Ames police complaint, the woman told officers Irving held her down, cut off a large portion of her hair and punched her repeatedly in the leg on Wednesday. Police said Irving acknowledged arguing with the woman, who lives with him and is the mother of their child, but he denied cutting her hair.
Police Commander Geoff Huff said the officers who responded to the scene noticed several bruises on the victim's legs and a large scratched area on the back of her leg.
Irving was being held in Story County jail on a charge of domestic assault with injury. His bond was set at $2,000 and a preliminary hearing was scheduled for Nov. 25. A judge also issued a no-contact order preventing Irving from seeing the woman or the child.
Iowa State spokesman Michael Green said the school was still gathering information on the situation and declined further comment. Online court records don't yet indicate whether Irving has an attorney.
Irving has started eight games for Iowa State this season, though he sat out last week's 21-17 loss to TCU because of what coach Paul Rhoads said was a health issue that was non-football related. Irving has two sacks, two blocked kicks and one forced fumble.
