Jordan's original suspension, which he already served two games of, was lifted because of the terms of the NFL's new drug policy that took effect on Wednesday. But he has now been suspended four games without pay for violating the NFL's Policy and Program on Substances of Abuse.
The defensive end released a statement saying he is currently undergoing treatment to "address my situation."
"I am working hard to become a better man and to make better choices in the future," he said. "I am especially looking forward to returning to the team. I also want to thank my family, Coach Philbin and the Miami Dolphins organization for their support."
The Dolphins released a statement saying they are "disappointed to learn of the result" but support Jordan "for proactively taking steps to voluntarily seek treatment to better himself."
Jordan recorded 26 tackles and two sacks in 2013. He will be eligible to return to the Dolphins active roster on Oct. 20.
