The 25-year-old continued the trend of prominent 49ers players retiring this offseason, and becomes the second promising young player to do so after teammate Chris Borland, 24, retired in March.
"I'm simply doing what's best for my body as well as my mental health at this time in my life," Davis said about his decision.
Davis started in every game he played for the 49ers since they drafted him in the first round of the 2010 draft.
"This will be a time for me to allow my brain and body a chance to heal," Davis added. "Many won't understand my decision, that's ok."
Six players were absent from the 49ers' OTA practice on Thursday, according to the San Jose Mercury News.
Those not present were wide receiver
OTA practices are voluntary and players are not required to attend.
Both players were listed as questionable on the team's final injury report, though it was reported early Saturday that Gore would in fact suit up for the game. Crabtree has yet to miss a game this season.
Brock, Culliver, Martin and Ventrone all came into the contest listed as questionable, but none of them will play. Stevie Johnson had been ruled out prior to Sunday. Both Josh Johnson and Anthony Davis are healthy scratches.
