A.J. Klein wasn't the only linebacker who surprisingly made a huge impact as rookie Dorian Williams also saw extended snaps in this game. The Bills third round pick had played only about 20% of the defensive snaps this season but only played 17 snaps total over the final six games of the season.
Williams would end up being asked to play alongside Klein for most of the game and put together a really impressive performance. He finished the game second on the Bills in tackles with eight total, including one tackle for a loss.
It will be interesting to see what the linebacker position looks like next week but they might have gotten some good news after the game. According to NFL Network's Ian Rapoport, Bernard suffered an ankle sprain and the X-rays were negative. It might be too much to overcome this week but he could be back at some point in the playoffs.
