The San Francisco 49ers announced Monday that they signed nose tackle Ian Williams to a two-year contract extension through the 2015 season.
"We are very pleased to extend the contract of a young, talented player like Ian," general manager Trent Baalke said in a statement. "He will have the opportunity to continue to grow in our defense, and we look forward to his future development."
Williams was an undrafted free agent out of Notre Dame in 2011. In two years with San Francisco, he has seven tackles in four games.
