Stanford, California - Stanford offensive lineman Branson Bragg has retired from football as lingering symptoms from a concussion and other mental health factors took their toll.

Bragg, who did not play in Stanford's first two games of the season, took to Twitter on Monday to announce the end of his career in a heartfelt message.

"I’m heartbroken to announce that I’ve decided to retire from football," Bragg wrote. "This was the hardest decision I’ve ever had to make, but with long-term lingering and intense symptoms stemming from a severe concussion I sustained in training camp, along with other mental health factors, I’m confident that stepping away is the best decision for me."

He added: "The past four years at Stanford have been everything that I could’ve hoped for, and I created countless lifelong bonds while living out my dream with the best teammates and support staff in the world."
