Former 49ers RT Anthony Davis contemplating a comeback?

SANTA CLARA, Calif. -- Anthony Davis stunned the San Francisco 49ers when he suddenly announced his retirement at age 25 in June, leaving the Niners with a huge hole at right tackle and little time to fill it in the offseason.

Veteran Erik Pears, who was signed for depth, has assumed the role, despite playing guard last season for the Buffalo Bills.

But might Davis, who said he needed to heal physically and mentally, be preparing for a comeback a soon as next season?

Niners coach Jim Tomsula was asked about Davis' comments on Tuesday and took the high road.

"Well, first of all, I'm not even thinking about the playing side with Anthony," Tomsula said. "It's well documented, we've talked about it, and he's taking care of Anthony and I'm really excited about that. I'm excited about hearing that he would like to come back with football. I think that speaks volumes of where he's at and how he's feeling.

"But, I like to just stay, that's a different time and a different place, but it does make you feel good. Obviously, things are going in the right direction for him."

Davis was one of five 49ers players to retire this past offseason, along with linebackers Patrick Willis and Chris Borland, defensive lineman Justin Smith and safety Bubba Ventrone.
