49ers agreed to terms with former Notre Dame nose tackle Ian Williams. Williams played nose tackle in Notre Dame's 3-4 defense, so he'll at least be familiar with the formatting of San Francisco's defensive system. It's also a great fit for the 6-foot-1, 319-pound prospect because the 49ers only have four defensive linemen under contract and are losing Aubrayo Franklin. Source: Evan Silva: Twitter.com
