UFC fans express concern for Conor McGregor as Irishman appears to spasm involuntarily during interview alongside co-star Jake Gyllenhaal

UFC star Conor McGregor has once again raised eyebrows with his erratic public appearance while promoting his new action film Road House alongside Hollywood superstar Jake Gyllenhaal.

The 35-year-old McGregor has not fought since July 2021, when he suffered a horrific broken leg in a second straight Octagon defeat at the hands of Dustin Poirier.

The Irishman is believed to have made a full recovery and has expressed his desire to take part in International Fight Week in June.

However, fans have grown concerned about his lifestyle during his time out and those concerns have not been alleviated by some of his recent interviews.

McGregor has promoted Road House heavily with a range of media duties but has behaved in a worrying manner on some occasions.

And The Notorious has become a topic of conversation again online after an interview with Sports Illustrated.

Viewers quickly noticed something was off with the Dubliner, who seemed extremely tired and far removed from his usual charismatic self.

McGregor, who appeared to be struggling to get his words out, continually shrugged his shoulders during the conversation, with some fans claiming he was convulsing.

The former champion’s complexion also seemed off, while he also appeared to be sweating next to Gyllenhaal, who, on the other hand, looked incredibly fresh.

“This is legitimately sad, I hope he gets the help he needs,” one viewer wrote on X, while another said “that was uncomfortable to watch.”

“That man will never fight again,” another X user wrote, as one claimed it appeared to be the product of “withdrawal symptoms.”

This latest incident comes just two days after McGregor confirmed plans to fight American rival Michael Chandler this summer.

The pair were the opposing coaches on The Ultimate Fighter last year and have been fighting ever since.
