RENTON, Wash. -- Less than three months after a cancerous kidney was removed, Seattle Seahawks defensive tackle Jesse Williams has returned to the field.

Williams was activated from the non-football injury list and took part in Seattle's practice on Thursday. It was his first action of the offseason after being diagnosed with papillary type 2 cancer in May and undergoing surgery.

According to statistics from the American Cancer Society, the average age of people diagnosed with kidney cancer is 64, and kidney cancer for those under age 45 is rare. Williams is 24.
