Anthony Davis retires from football

The offseason from hell continues in San Francisco. Starting right tackle Anthony Davis -- the 11th overall pick in the 2010 Draft and starter of 71 games over the past five seasons -- has decided to call it a career. Or, at the very least, he'll not be playing in 2015. The 25-year old released a statement.

"After a few years of thought, I've decided it will be best for me to take a year or so away from the NFL. This will be a time for me to allow my Brain and Body a chance to heal. I know many won't understand my decision, that's ok. 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."

Davis becomes the fourth 49er to retire during this tumultuous offseason that also saw the departure of head coach Jim Harbaugh, offensive coordinator Greg Roman, and defensive coordinator Vic Fangio. Justin Smith's retirement at the age of 35 was expected, but Patrick Willis' (age 30) and Chris Borland's (age 24) decisions to walk away from the game came as shockers to everyone.

The Niners also lost key starters and role players in Frank Gore, Mike Iupati, Michael Crabtree, Ray McDonald, Dan Skuta, Chris Culliver, Perrish Cox, Brandon Lloyd, and Stevie Johnson.

San Francisco will now have to scramble to fill the vacant right tackle spot. Erik Pears is a likely candidate, but Alex Boone could be an option as well. Rookies Ian Silberman and Trent Brown could be options as well.
