The way the week was shaping up, the Buffalo Bills looked like a team that would have their full roster available to play against the Atlanta Falcons in Toronto on Sunday. During the final day of practice this week, one of their best players was nowhere to be found. Defensive lineman Kyle Williams was not on the practice field for the first time this week. In normal weeks, Williams would receive each Wedendsay off to rest his right Achilles. The Bills are coming off their bye however, which could have given the defender enough time to rest it over the weekend. He did participate in practice on Monday, Tuesday or Wednesday, so there have been no specific reasons given for his absence on Friday just yet. The Bills had Thursday, Thanksgiving Day, off from work. The team's practice is still happening at One Bills Drive. Be sure to come back later to see what head coach Doug Marrone has to say about Williams not practicing.
