Von Miller has been suspended four games for violating the rules of conduct

Buffalo Bills pass rusher Von Miller has been suspended four games without pay for violating the NFL's personal conduct policy, the league announced Tuesday.

Miller will be eligible to be reinstated on October 28 following the Bills' Week 8 game against the Seattle Seahawks.

The suspension stems from allegations that Miller assaulted his pregnant girlfriend last year. Miller filed an arrest warrant on Nov. 30 for third-degree assault.

Miller said the allegations were false and “exaggerated.”

According to a police affidavit about the alleged assault on Nov. 29, Miller twice placed his hands on the woman's neck, ripped out a piece of her hair and threw her onto a couch. The woman was treated for minor injuries, including bruising to her neck, officials wrote.

Miller said back in July that no formal charges were ever filed and he assumed the case was closed. The NFL had conducted a separate investigation.
