"We were made aware of a police matter earlier this morning regarding Mark Walton," Miami general manager Chris Grier said in a statement. "We hold our players to a high standard and take these matters very seriously. We will have no further comment at this time."
According to a Broward County (Fla.) arrest report, Walton allegedly pushed the victim against a wall and punched her several times in the face and head after an argument. The victim is five weeks pregnant, according to the report, and Walton is the father of the child and was made aware of the pregnancy Sunday.
The 22-year-old running back was given a second chance in Miami this season and compiled 201 yards on 53 rushes in seven games.
