Miami Dolphins defensive end Dion Jordan has been suspended for the 2015 season by the NFL.

The 25-year-old missed the first four games of the 2014 season for violating the league's policy on substances of abuse, which was extended by a further two matches for another infraction.

Jordan will now miss the 2015 campaign for breaching the policy for a third time after his sample was diluted.

The Dolphins traded up to select Jordan with the third overall pick in the 2013 Draft, and he has recorded just 46 tackles and three sacks in his two years in the league.
