Although he has not appeared on the Bills’ injury report at any point during the first four weeks of the season, nor has he missed any practice time, Mario Williams has said his sore left wrist is hindering his play. Adam Schefter of ESPN reports the NFL will be looking into this. According to the NFL policy on Injury reports, "All players with significant or noteworthy injuries must be listed on the report, even if the player takes all the reps in practice, and even if the team is certain that he will play in the upcoming game. Sal Maiorana of the Rochester Democrat and Chronicle reports Williams first mentioned that he’d hurt his wrist following the Bills’ 48-28 loss to the Jets on opening day, a game in which Williams made just one tackle and never came close to sacking Mark Sanchez. He said at that time the injury occurred late in the preseason, but he didn’t expect it to be a problem moving forward. For the past three games he has played with a cast, and Wednesday, when pressed about the injury, he admitted he’s having a difficult time coping with it. Source: The Redzone
