“The 49ers organization thanks Anthony for his contributions to our team over the last five seasons and wishes him the best as he moves on from the game,” general manager Trent Baalke said through a team statement. 

I hope you too have the courage to live your life how you planned it when day dreaming to yourself growing up. Your Life is Your dream and you have the power to control that dream. Im simply doing what’s best for my body as well as my mental health at this time in my life.

Sincerely,  Anthony Davis"

Davis, 25, started immediately as a rookie and did not miss a game until he was sidelined for a total of nine last year with an MCL sprain and a concussion. He signed a five-year extension in 2013.

Davis isn’t necessarily retiring, as teammates Justin Smith, Chris Borland and Patrick Willis have done this offseason.
