Per Brent Zwerneman of the Houston Chronicle, the Brazos County sheriff's office charged Walker with assault causing bodily injury to a family member and interfering with emergency requested for assistance stemming from an alleged incident Friday.
Zwerneman added that the "family member was not named" in the police report.
Walker is currently being held at Brazos County Detention Center, and no bond has been set.
A Texas A&M athletic department spokesman told Zwerneman that Walker is suspended, per the school's athletic department policy.
Walker is entering his junior season at Texas A&M.
