Dion Jordan is currently one of the biggest busts in recent NFL history, he could be preparing for a comeback.

Jordan's has apparently been working out in San Francisco and the owner of the gym posted an Instagram photo of Miami Dolphins defensive end, who appears to be in shape.

Jordan's agent posted a tweet touting his client, saying the former Oregon star will be the "comeback player of the year" presumably for the 2016 season.

comeback player of the year. @dionj95 working with the best @tareqazim @empowersf redemption song....stay tuned... — Doug Hendrickson (@DHendrickson41) May 5, 2016

Jordan, the third overall pick of the 2014 NFL Draft, missed the entire 2015 season while serving a one-year suspension after multiple violations of the NFL's substance abuse policy. However, Jordan is eligible for reinstatement for the 2016 season, but commissioner Roger Goodell has not approved Jordan's reinstatement.

The Dolphins have said they would welcome 6-foot-6, 275-pound Jordan back, provided he proves he still loves the game. The Dolphins could use Jordan. Defensive end Olivier Vernon, who led the Dolphins in sacks in 2015, signed a free agent contract with the New York Giants. Defensive end Cameron Wake is rehabbing a torn Achilles tendon. The Dolphins did sign defensive end Mario Williams.
