Sylvester Stallone almost took a very different career path before becoming an actor, writer, and director.

The "Rocky" star posted throwback photos on Instagram of himself playing polo, revealing that he once believed the sport was his "destiny."

"Fun fact of the day: Stallone means Stallion in Italian. Funny but true - and for a good part of my life, I pursued my passion for polo, believing it was my destiny. But life had other plans and sidelined my dreams," he wrote in the caption.

He continued, "Yet, I refused to let that be the end of my journey. When one door closed, another opened— only this time, it was one of creativity and resilience. I embraced writing and acting with fervor, shaping a path I never imagined."

SYLVESTER STALLONE WARNS ‘NEVER DO YOUR OWN STUNTS’ AFTER 7TH BACK SURGERY

Stallone concluded the post with words of encouragement, writing, "So, when life knocks you down, remember: Get back on your horse. Keep punching." 

The 77-year-old previously detailed his polo dreams in his Netflix documentary, "Sly."

At 13, Stallone had become a nationally ranked polo player while living in Maryland with his father following his parents' divorce.

However, Frank Stallone Sr. appeared to be jealous of his son’s success, and Stallone recalled that in the middle of a game, his father began screaming at him from the stands, and then came onto the field.

"I was going for a nearside backhand, and I didn’t do anything wrong — he goes, ‘You’re pulling too hard on the horse!’" he said.

"[Frank] comes out of the stands, grabs me by the throat, throws me on the ground, takes the horse, and walks off the field."

He added, "I laid there and I went, ‘I never want to see a horse again in my whole life.’"

Stallone did play polo again at 40 and even invited his father to play with him in a game. But during the match, Frank Sr. hit Stallone in the back, and he fell off the horse, which nearly trampled him. Stallone recalled, "He just rode away."
