"Creed" has not only been a knockout in the box office, but it appears actor Michael B. Jordan felt that same feeling. Sylvester Stallone wants fans to know that Jordan actually did roll with the punches in the film. The "Rocky" actor appears to have captured a moment on video where Jordan physically took a hard punch to the face during the filming of a fight scene.

Stallone posted a brief behind-the-scene video on Twitter showing Jordan getting knocked out for real.

"Michael B Jordon, 'young creed and 'getting KO'd for real! But he got up and did it again! That's called guts!!'" the 69-year-old actor captioned the clip.

In the video, Jordan and another boxer pretend to punch each other as the director begins to countdown. When action is yelled, Jordan takes a big right hand to the face and crumbles to the mat. You can watch the video below:

"Creed" has been a huge box office success since it was released on Nov. 25 and has gotten very high praise from film critics. The movie currently has a rating of 8.6 on IMDB and a 93 percent freshness score on Rotten Tomatoes. As of Dec. 4, the film has grossed over $64 million in the United States.

Talks of a sequel have already started, especially after Jordan came out publicly saying he'd like to return for "Creed 2," so he can see how much further his character goes. "Creed" tells the story of Adonis Johnson, who is the son of Apollo Creed from previous "Rocky" movies. Adonis wants to follow in his father's footsteps and become a boxer. He gets a little help from the retired boxer Rocky Balboa (Stallone).

"Creed" is the latest installment in the "Rocky" movies, which are one of the most successful sports movie franchises of all time. Balboa's story played out over six films from 1976 through 2006.

"Creed" is in theaters now. You can watch the trailer below:
