Nose tackle Ian Williams signs one-year deal with 49ers

SANTA CLARA, Calif. (AP) Free agent nose tackle Ian Williams signed a one-year contract Wednesday with the San Francisco 49ers that could pay him up to $6 million.

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. His status is unclear heading into the team's first offseason program under new coach Chip Kelly.

Williams 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 defensive lineman broke his leg in a Week 10 game during the 2014 season and wound up on injured reserve for the second straight year.

Williams had 65 tackles, a sack and a forced fumble while starting all 16 games last year during the 49ers' 5-11 season. San Francisco missed the playoffs for the second straight season and first-year coach Jim Tomsula was fired, replaced by Kelly in January.
