SANTA CLARA, Calif. (AP) Free agent nose tackle Ian Williams signed a one-year contract Wednesday with the San Francisco 49ers.

On March 9, Williams reached agreement on a five-year deal that was restructured once his doctors in Miami shared findings about an undisclosed injury with the 49ers medical staff.

He began 2013 as starting nose tackle, then sustained a season-ending lower leg injury in a Week 2 loss that year on a cut block by Seattle right guard J.R. Sweezy. Williams underwent four surgeries near the ankle - having screws and plates put in and then removed - and began the 2014 training camp on the physically unable to perform list following an offseason setback.

The 26-year-old broke his leg in a Week 10 game during the 2014 season and wound up on injured reserve for the second straight year.
