49ers offensive lineman Anthony Davis has informed the team that he’s retiring.

Davis had retired before last season, returned this season and had contemplated retirement before the regular season started. He suffered a concussion in practice following the season opener and isn’t planning to play again.

The team announced the news with a one-sentence statement.

A first-round pick in 2010, Davis started 71 of 72 career games at right tackle. He first retired after being limited to seven games in 2014.
