SAN FRANCISCO (AP) Right tackle Anthony Davis has been reinstated by the NFL after an 11-month retirement that he planned to come back from all along.

The San Francisco 49ers made the announcement Saturday ahead of their first day of training camp Sunday under new coach Chip Kelly.

Davis was the 49ers' first-round draft choice, the 11th overall pick, in the 2010 draft out of Rutgers. He was affected by a concussion late in the 2014 season.

On June 5, 2015, at age 25, Davis announced his retirement in another surprising offseason departure last year for the 49ers. He became the fourth prominent San Francisco player to retire in a three-month span, joining linebackers Patrick Willis and Chris Borland and defensive end Justin Smith. The announcement came four days before the team's mandatory June minicamp.

Also Saturday, San Francisco placed nose tackle Ian Williams on the reserve/non-football injury list.
