Dallas, Texas - Two-time Super Bowl champion linebacker Von Miller turned himself in on Thursday after police in Dallas, Texas, alleged in an arrest warrant that he assaulted his pregnant girlfriend.

The Dallas Police Department announced in a statement that Miller and the alleged victim had a verbal argument that led to the NFL star assaulting the woman, based on a preliminary investigation to a "major disturbance call" on Wednesday.

Police said Miller left the scene before police arrived while the alleged victim was treated for minor injuries. WFAA television in Dallas, citing multiple police sources and court documents in its report, said the woman was Miller's longtime girlfriend.

Later Thursday, Dallas police confirmed that Miller, a linebacker for the Buffalo Bills, turned himself in to police in suburban Glenn Heights.

Miller, the career leader in NFL quarterback sacks among active players, was the Most Valuable Player in Super Bowl 50 for Denver in a 24-10 triumph over Carolina in 2016 with six tackles, two forced fumbles, and 2.5 sacks.

He also helped the Los Angeles Rams win the 2022 Super Bowl before signing a six-year deal worth $120 million with Buffalo the following month.
