Greg Hardy got a first-hand look at his new profession Friday night.

Hardy, the former Cowboys' defensive lineman, was at Legacy Fighting Championships at The Bomb Factory in Dallas to see what he wants to be doing soon -- fighting mixed martial arts in a cage.

Hardy, who wore a LeBron James Cleveland Cavaliers jersey, is training every day in Dallas. Having been shunned by the NFL -- including the Cowboys -- after his off-field and professional behavior, Hardy is already experiencing the difficulties of MMA.

"The hardest part is keeping into it mentally," Hardy said. ... And "conditioning, man these guys can go for days. I'm waiting for the six pack to come in."

His agent, Adie von Gontard, confirmed that he's already been contacted by organizations interested in Hardy. Legacy, a feeder league of the UFC, is one of the organizations interested.

Asked when he could fight, Hardy said, "When I'm ready. It's about the details. Putting in the work. Working to get all the tools together."

Hardy has a long way to go. He has no MMA experience. It could take him years to develop into a fighter.

Hardy had seen a UFC event in person before but never a local card in an intimate setting. He was impressed with the ground game of the Legacy Fighters.

"I know how tough it is," he said.

Hardy said his favorite UFC fighters included Jon Jones, (Big Country) Roy Nelson and Cheick Kongo.

Hardy has watched the Cowboys and wishes them well.

"God bless them all," Hardy said. "They're doing great. They don't need me."

When asked if he would go with Dak Prescott or Tony Romo, Hardy said, "Both. If you can run a double QB like a double running back, that's what I would do."

The Cowboys gave Hardy new life in the NFL last season after he was suspended for most of the 2014 season amid a domestic violence case.

Then, after not being rehired by the Cowboys amid on-field incidents and word of locker-room issues, he went on ESPN to talk about the domestic violence case. That interview was pitched as his chance to redeem himself, but the public opinion afterward was that he failed miserably.

He was recently arrested on cocaine charges last month in Richardson.
