The third quarter was a bit shaky (as have all the third quarters the Bills have played this season have been) but Buffalo played an overall good game.

Bills quarterback Josh Allen threw for 288 yards and two touchdowns in the win, but there was a scary moment for Bills fans late in the first half when Allen left the field grimacing in pain after landing funny on his left arm/shoulder.

Those on Twitter pointed out they thought that there ight have been a dirty hit on Allen when he landed on his arm. He was already engaged with defensive back Keisean Nixon, when defensive end Arden Key launches into Allen's helmet.

Luckily, Allen came back at the start of the second half and didn't miss any snaps.

Allen is fun to watch but these are the kind of plays that make Bills Mafia nervous. It makes Allen special, since most quarterbacks can't do the things he can running, but you would like him to get rid of the ball a bit quicker.

Do you think it was a legal hit or should there have been a flag?
