Bills defensive tackle Kyle Williams will retire following the Dolphins game. The 13 year veteran played his entire career here. Drafted in the 5th round in 2006 from LSU, he made 5 Pro Bowl appearances. WILLIAMS CITED FAMILY REASONS FOR RETIRING. HE HAS BEEN A FIXTURE OF THE BILLS ORGANIZATION, CONTRIBUTING BOTH ON AND OFF FIELD. COACH McDERMOTT SAID HIS RETIREMENT IS THE WORST CHRISTMAS PRESENT HE COULD RECEIVE. EXTENDING ALL BEST WISHES TO KYLE AND HIS FAMILY, WE ARE GRATEFUL AS 1BUFFALO.
