Miami Dolphins defensive end Dion Jordan has been reinstated on a conditional basis by the NFL following a yearlong suspension for his latest violation of the substance-abuse policy.
The NFL said in a release that Jordan can join Dolphins training camp for meetings and conditioning work. He can practice and participate in preseason games once "arrangements have been confirmed regarding Jordan's clinical resources in Miami," the league said.
Jordan can become eligible for Week 1 of the regular season after a follow-up meeting with the NFL.
He was not in attendance for the first day of Dolphins camp Friday.
The third overall pick in the 2013 draft, Jordan was suspended for the entire 2015 season after a drug test sample was diluted. He has been suspended three times during his brief NFL career.
He has played in only 26 games in his career with one start, totaling 46 tackles and three sacks. The Miami group that drafted Jordan is gone, and he returns to a new coaching staff led by Adam Gase.
"We're still at the beginning stages of this. I know that's the boring answer, but that's what it is right now," Gase said. "... The good thing is we will have a plan. We will have an understanding on what we need to do and steps we need to take moving forward."
Gase said he wasn't sure what it would take for Jordan to earn the trust of the team.
"I don't know him. That's hard for me to answer," Gase said. "I just know that when he gets here, it's a fresh start with me. So I guess that's really all that matters."
Jordan had been suspended without pay since April 2015. He applied for reinstatement in May, telling USA Today Sports he "never" had a drug problem. He didn't fail or miss any drug tests while undergoing them weekly over the past year, his agent said in May.
He excelled as a pass-rusher at Oregon, but his lack of productivity with the Dolphins has raised questions about his best position. The Dolphins are deep at defensive end with newcomers Mario Williams, Jason Jones and Andre Branch and with Cameron Wake returning from Achilles tendon surgery. They might consider moving Jordan to linebacker.
Jordan's first suspension was for the first four games in 2014, and two more games were subsequently added for an additional violation.
