Conor McGregor said he feared his career was over while speaking from a hospital bed in new documentary trailer

• Conor McGregor said he once feared his career was over in a trailer for a new documentary.
• The upcoming feature is a four-part series that details McGregor's comeback from injury.
• He famously delivered an unhinged rant shortly after suffering a horror leg break in 2021.

Conor McGregor said he worried his career in ultimate fighting was over while speaking from a hospital bed in a trailer for an upcoming documentary on Netflix called "McGregor Forever."

The 34-year-old has not competed since suffering a broken leg and losing by first-round doctor's stoppage to Dustin Poirier in a bout in July 2021.

McGregor's leg buckled under its own weight, fracturing his left tibia and fibula.

In one scene in the documentary, he appeared unfazed at the scale of the injury as he spoke while medical professionals strapped his leg before placing him on a stretcher to take him out of the arena after the conclusion of the Poirier fight.

The Irishman has since been linked with a comeback bout later this year against lightweight rival Michael Chandler.

'McGregor Forever' is a four-part series on Netflix

The four 60-minute episodes of the documentary series looks at McGregor's recovery from injury as well as an in-depth look at the "controversial superstar," Netflix said in a release.

"Conor is unlike anyone I've ever collaborated with. As one of his trainers described him, he's an entirely unreasonable man," said Gotham Chopra, director of McGregor Forever, in a statement sent to Insider.

"And for that reason, he's impossible not to watch and be fascinated by. Don't look away, because I guarantee you, you will definitely miss something inexplicably wild."

According to the documentary's synopsis, the series "will put you in the room with one of the greatest mixed martial arts stars on the planet as he takes on the most important battle of his career."

The McGregor Forever documentary airs on May 17.

It remains unclear when McGregor will fight Chandler in the UFC, yet a reality TV show they filmed together as rival coaches for the popular The Ultimate Fighter (TUF) program begins on May 30 and concludes on August 15.

Typically, the coaches fight each other sometime after the last TUF episode.
