Fans express concern for Conor McGregor after interview appearance alongside Road House co-star Jake Gyllenhaal

Fans have voiced their concern for Conor McGregor after he took part in an interview alongside Road House co-star Jake Gyllenhaal.

The former multi-weight UFC champion, who hasn't fought since breaking his leg against Dustin Poirier at UFC 264, made his big screen debut in the remake of 1989 classic Road House.

As a result of his much-anticipated appearance in the Hollywood blockbuster, McGregor will reportedly earn over £4 million, making him the highest-paid debutant actor of all time.

It has been an extremely busy period for the Irishman, who continues to promote the film by speaking to multiple media outlets, including a recent chat with Sports Illustrated.

He opened up about his acting debut, as well as the fight scene realism, while sitting next to Jake Gyllenhaal, who portrays troubled former UFC middleweight fighter Elwood Dalton.

Speaking about working alongside Gyllenhaal, who has appeared in films such as Nightcrawler, Source Code and October Sky, McGregor was highly complimentary of his co-star.

“Jake’s a consummate professional, 75 movies made. I’m blessed to have entered into the movie alongside him. He was patient with me, he gave me guidance, and I just took it," the Irishman said.

"You know, we have a good rapport on set. He has 75 movies made, I have 75 barfights made and that’s it, we had a good back and forth.”

But it was McGregor's body language that sparked concern in the comments section. The 35-year-old looked tired and struggled to get his words out at times, shrugging his shoulders throughout.

Here's how fans on social media reacted to the above interview with Sports Illustrated.

One said: "Christ that’s one of worst I’ve seen him. Can’t stop twitching and shrugging," while another commented: "Man I like Conor hope he is okay."

A third wrote: "Jake looks genuinely concerned for Conor here. Sad to see."

A fourth said: "Take care of yourself Conor please," while a fifth added: "Conor has really begun looking tired at this point of the promotion, do you agree?"

Earlier this week, McGregor said he's already received a call from the UFC about his much-anticipated return to the Octagon.

Speaking to ESPN, he said he will be returning to action this summer against Michael Chandler, although the exact date and event are not yet known.

"We got confirmation a few days ago that it's all systems go," he said. "And 'The Mac', 'The Notorious' will be returning to the UFC Octagon this summer."
