Williams will have his contract extended by one year and $10.5 million, ESPN.com reports. This keeps the Pro Bowl defensive lineman locked up through 2017 if the Bills so choose, while also likely giving the team some extra wiggle room for the current free agency period in what's already been an aggressive offseason for the team. Marcell Dareus might be next on the contract front, at which point the Bills would have a fierce front four of Kyle Williams, Mario Williams, Dareus, and Jerry Hughes all locked up.
