May 14 (UPI) -- Free agent defensive end Dion Jordan had his appeal denied for a 10-game suspension Tuesday.
Jordan was reprimanded for violating the NFL's performance-enhancing drug policy after taking Adderall. He was previously approved to take the medication for ADHD, but his therapeutic use exemption had expired.
"I made a mistake," Jordan told NFL Network. "I feel like the person that I am, I'm ready to move forward, I've been ready to move forward, with this specific issue. I've been working really hard with myself outside of football, and I can see the progress as a young man, as Dion Jordan I can see it.
"My whole lifestyle -- it's been a 180-degree change. I [expletive] up, man. I can't fix this [expletive]. It is what it is. But I know what I can't do and what not to do compared to the mistakes I've made in the past."
Jordan, 29, was the No. 3 overall pick in the 2013 NFL Draft. The Oregon product appeared in 16 games during his rookie campaign for the Miami Dolphins, but never blossomed into a star pass-rusher. The Dolphins cut Jordan in 2017, after he was suspended twice before for violating the league's substance abuse policy. He missed the entire 2015 season with a suspension.
Jordan appeared in five games for the Seattle Seahawks in 2017. He appeared in 12 games last season for the Seahawks.
The 6-foot-6, 284-pound pass-rusher has 8.5 sacks, four passes defensed and two forced fumbles in 43 career appearances during his NFL tenure.
