The 49ers welcomed fullback Bruce Miller back into the fold on Friday, while offensive tackle Anthony Davis announced his retirement from professional football
"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," Davis said in a release. "This will be a time for me to allow my Brain and Body a chance to heal. I know what won't understand my decision, that's OK."
Davis sustained a concussion in a win over the New York Giants in mid-November and endured a slow recovery process.
"It's scary when your brain's not working how it's supposed to," Davis said at the beginning of December while his symptoms lingered. "It's like a white fog. You look out, it's like a white fog."
Davis, whom the 49ers selected with the No. 11 pick in the 2010 draft, became the fourth 49er to retire this offseason along. He followed Patrick Willis, Justin Smith and Chris Borland.
Meanwhile, Miller was back in the building in Santa Clara for the first time since he was arrested on March 5 after getting getting into an argument with his then-fiancee. Miller smashed the woman's phone by throwing it against a wall but disputed the notion that he physically touched her. "Didn't happen," he said.
After staying away from the team's offseason program, Miller is ready to do whatever it takes to get his career back on track with the franchise.
"I'm completely committed to taking the steps necessary to be here and be part of this team," Miller said. "It's great to be back with the guys."
