On Friday, 25-year-old offensive tackle Anthony Davis became the latest member of the 49ers to retire. The 2010 first-round pick follows former teammates Patrick Willis, Justin Smith and Chris Borland out the door, and the 49ers now must fill another hole on a roster that already had plenty of questions.

And while losing Davis, who started 71 games in five seasons, only complicates things for first-year coach Jim Tomsula, there is some good news. Davis doesn't plan to stay retired forever.

So there's that.

Earlier Friday, Davis explained his decision to (temporarily) hang it up.

"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," he said in a statement. "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. I'm simply doing what's best for my body as well as my mental health at this time in my life."

The news didn't seem to come as a surprise to the 49ers, presumably because retirement press conferences have become a regular occurrence this offseason.

"I can't say it was shocking at all," Tomsula told reporters after Davis' announcement. "Anthony's been working on himself right now, that's what he's been doing.

"Look, Anthony wants to step away and he wants to get his mind and his body right and that's where he wants to go and he has every right to do that. We wish him the best."

So there appear to be no hard feelings between Davis and the organization, and president Jed York even sent Davis this tweet on Friday evening.

For now, the 49ers are in the market for a tackle. Tomsula, at least publicly, isn't concerned.

"I don't think it's a huge blow to this team," the first-year coach said. "I wouldn't categorize it that way. We've got some guys doing some really good things right now that we're really excited about moving into training camp. But, no we're really excited about the guys that are here. That's what we've said all along. The focus is on the guys that are here and the guys that are doing what they are doing."
