Allen is in concussion protocol, according to the team.
Jones was flagged, but there was no penalty as it was offset by an offensive flag on the same play.
"I haven't seen it. You know, I have to watch it on film. We're just running around playing football. There's no intent to ever hurt anyone, you know, we're just playing good, clean football," Jones told reporters after the game. "I don't think anybody ever really tries to go helmet-to-helmet. Everyone's just flying around wanting to make plays, wanting to make starts."
Al Riveron, the NFL's head of officiating, told The Buffalo News' Vic Carucci that the play did not "rise to the level" of warranting a disqualification.
"That's the first thing that came out of my mouth on the sideline, if one of us did that to 12 [Tom Brady], we wouldn't have been in the game anymore," Hyde said. "There's no way, there's no way we would've continued to play in that game."
After some assistance on the field, Allen walked off under his own power to the injury tent and shortly thereafter ran off the field to the locker room.
