Dion Jordan has been suspended four games for violating the NFL's policy on performance enhancing substances.

Jordan, the No. 3 overall draft pick in 2013, recently said he had gained 17 pounds of muscle compared to last season, when he didn't get much playing time because there were concerns about his strength.

"We were disappointed to learn about Dion's suspension," Dolphins coach Joe Philbin said. "Dion has accepted responsibility for his actions and is committed to improving, both on and off the field, in preparation for the upcoming year."

Jordan's suspension hurts Miami's depth at defensive end.
