NFL Legend Tom Brady Makes Career Announcement on Thursday

However, it appears that another big change is on the way. In an Instagram post on Thursday, Brady revealed NOBULL nutrition.

"I’m proud to introduce you to NOBULL nutrition, the next step in our team’s commitment to helping people get stronger, mentally, emotionally, and physically," the post read, "NOBULL nutrition is a new line of protein and electrolyte products with its own science and mentality that I believe in.

"NOBULL nutrition was born from the work we accomplished at TB12 Performance, which I co-founded with my best friend Alex Guerrero in 2013. I want to sincerely thank everyone who supported the brand and believed in the mission and all that we achieved.

"TB12 helped shape my perspective on performance and wellness at a pivotal time in my life, and with NOBULL nutrition we’ll take the next step and continue to innovate the best products in the industry. Thank you for your loyalty, trust, and commitment to better performance. I can’t wait for you to try it."

Though he's already been working with NOBULL, after making the announcement, TB12 revealed it will be "winding down," as it approaches this "next chapter."

Along with its new line of NOBULL nutrition, the company sells apparel ranging from joggers, footwear, tank tops, hoodies and shorts.

"Your NOBULL(expletive) wellness routine just leveled up," the company also posted. "Introducing NOBULL nutrition. From footwear and apparel to protein and electrolytes, we’re here to help you get stronger and provide the tools you need to do the work."

As Brady prepares for another big venture in his post-playing career, NFL fans will soon be hearing him in the booth. He and his Fox crew will be announcing the San Francisco 49ers and Seattle Seahawks divisional-round matchup at 8 p.m. ET Saturday.
