DAVIE, Fla. -- Miami Dolphins running back Mark Walton has been suspended four games for violating the NFL conduct and substance abuse policy.
The four-game league suspension, which is without pay, stems from Walton's three offseason arrests in the span of three months between January and March, a source told ESPN.
The Dolphins had been in communication with the NFL for several weeks and they were aware that a suspension was likely coming before they traded Kenyan Drake to the Arizona Cardinals for a conditional sixth-round pick last month.
