Williams underwent offseason surgery to repair a bone spur on his heel and missed the entire spring. He's nearing 100 percent now. "As of now he's full go," said GM Doug Whaley.

Bills.com confirms DT Kyle Williams is recovering from surgery on his right Achilles' tendon.

Williams had left Achilles' surgery last year. While he avoided a complete rupture of the right Achilles' -- it was "frayed" -- he's yet to be medically cleared to participate in any workouts. Last year's rehab of a similar injury sidelined Williams for five months. Williams remained highly effective, grading out as Pro Football Focus' No. 3 defensive tackle behind Geno Atkins and Gerald McCoy. The buildup of surgeries is still a concern.
