Announce went on about how it wasn't that late as if the refs made a bad call. The announcers total neglected where the contact occured. The ref even announced it as a high hit. He is the rule that applies:

Roughing the Passer
ARTICLE 9. a. No defensive player shall unnecessarily rough a passer, when it
is obvious the ball has been thrown. The following actions are illegal, but not
limited to:
1. Targeting fouls as noted in Rules 9-1-3 and 9-1-4.
2. Forcible contact to the head or neck area that does not meet the
requirements of Rule 9-1-4 (also reference Rule 9-1-2).
3. Forcible contact that is avoidable after it is obvious the ball has left
the passer’s hand. (Exception: A defensive player who is blocked by a
Team A player[s] with a force so that they have no opportunity to avoid
contact with the passer. However, this does not relieve the defensive
player of responsibility for personal fouls as described in elsewhere in
this section.).
4. Forcibly driving the passer to the ground and landing on the passer with
action that punishes the player.
5. Any action that is a personal foul as described elsewhere in this section.
b. When an offensive player is in a passing posture with one or both feet on the
ground, no defensive player rushing unabated shall hit the player forcibly at
the knee area or below. The defensive player also may not initiate a roll or
lunge and forcibly hit this opponent in the knee area or below. [Exceptions:
(1) It is not a foul if the offensive player is a runner not in a passing posture,
either inside or outside the tackle box. (2) It is not a foul if the defender
grabs or wraps this opponent in an attempt to make a conventional tackle
without making forcible contact with the head or shoulder. (3) It is not a
foul if the defender is not rushing unabated or is blocked or fouled into this
opponent.]
For paragraphs a and b, the penalty is added to the end of the last run
when it ends beyond the neutral zone and there is no change of team
possession during the down. (A.R. 9-1-9-II-III)
