ORCHARD PARK, N.Y. >> Buffalo Bills edge rusher Von Miller was suspended four games by the NFL on Tuesday for violating the league’s personal conduct policy.

The NFL did not reveal the reason for the suspension, which comes as Buffalo (3-1) prepares to play at the Houston Texans on Sunday. Miller, the NFL’s active leader in sacks, is eligible to rejoin the Bills ahead of their home game against Miami on Nov. 3.

Miller was accused last November of assaulting his pregnant girlfriend at their home outside Dallas during the Bills’ bye week. He turned himself in to police after being accused of third-degree felony assault of a pregnant woman, which is punishable by two to 10 years in prison and a $10,000 fine.

The woman and Miller have been in a relationship for seven years and have two other children together.

No charges have been filed. Miller said in July he considered the case closed based on feedback from his attorneys.

“My life is all about football right now and my kids, and being the best teammate and best football player I can possibly be,” he said at the time. “I’m happy to be here with the Buffalo Bills. I’m happy to just be in this moment, living my life and do the things that we do normally.”

The 35-year-old Miller has three sacks in four games this season.
