Stallone shot to fame when he wrote and starred in "Rocky," a movie about a heavyweight boxer who fights for the world title. He has since starred in five sequels, which spawned spin-off sequels "Creed" and "Creed II."
"Eye of the Tiger," the theme tune from "Rocky III," has frequently been used as the entrance music for famous fighters like the eight-weight world champion Manny Pacquiao, and the impact Stallone has had on the sport was immortalized forever when he was inducted into the Boxing Hall of Fame in Canastota, New York, in 2011.
When asked whether the company is worried about this, Stallone told TMZ Sports "yeah we are."
But Stallone said McGregor should be "inspired" by recent events in his life and that he should use all of that energy, both good and bad, as a means of fueling his comeback to the UFC.
Speaking as McGregor, Stallone said: "Okay, I've gone through a very rough time. I've been somewhat publicly humiliated. I'm at a crossroad in my life I have to overcome an incredible opponent who seems invulnerable."
"This is a crossroad in his life. If he can't overcome his fear and beat this man, I think it'll plague him for the rest of his life."
Stallone said McGregor lost in the fourth round of that unforgettable UFC 229 event because he got "resentful, prideful, and arrogant." He added: "He put his hands down he walked right up to that gentleman and he just got smashed in the face when he could have been defensive. There was no Plan B. Not even a Plan A minus."
McGregor and Nurmagomedov are UFC Gods
A rematch between the lightweight champion Nurmagomedov and the former two-weight champion McGregor has been raised before, most prominently by McGregor himself, but they are currently serving suspensions for the roles they played in post-fight brawls that marred the show.
Regardless, a prospective rematch remains something Stallone would love to see as they are "two UFC Gods." He added: "I wanna see a guy that leaves everything on the table."
On McGregor's recent arrest, Stallone had seven simple words of advice for the fighter: "Keep smiling. You can't critique a smile."
