DAVIE, Fla. (AP) - The Miami Dolphins say defensive end Dion Jordan has been suspended four games by the NFL for violating the league's policy on performance-enhancing substances.
Jordan will be able to participate in training camp and preseason games. Once the regular season starts he will not be permitted to be part of the Dolphins' active roster until Sept. 29.
Jordan said Thursday in a release from the team that he tested positive for a stimulant and takes "full responsibility" for the test results.
Jordan was the third overall pick in the 2013 draft out of Oregon. He says he added more than 15 pounds of bulk this offseason in an effort to improve his game.
He played in all 16 games with Miami a year ago, with 26 tackles and two sacks.
