After racking up 38 sacks between 2012-14, Williams had just five sacks in 909 snaps last season. He was released by the Bills following a disappointing year playing linebacker in Rex Ryan’s 3-4 system.

In his first game with the Dolphins, defensive end Mario Williams had a sack. He also, however, suffered an injury.
According to Armando Salguero of the Miami Herald, Williams has a concussion.
He’ll be required to pass an independent neurological exam before returning to practice. He then will be required to pass a separate exam before he’ll be able to play.
The Miami defense had three sacks of Seahawks quarterback Russell Wilson. On one of them, Wilson injured his ankle.
