Buffalo Bills defensive end Mario Williams informed the team about his surprise wrist surgery last week via text, ESPN.com reported Sunday. Williams did not show up to the Bills facility last Monday before texting a trainer and a defensive line coach to inform them he was getting a second opinion on his wrist and that he was having arthroscopic surgery. He then texted that he would return to practice this Monday and be ready to play Nov. 4 against the Houston Texans. Buffalo had a bye this past week. The Bills were fined $20,000 for failing to disclose Williams' wrist injury earlier this season.
