I'm not sure exactly where it is in the rulebook, but I think it's part of the Replay Review rules. It's referred to as an exception for an "inadvertent whistle."
I'm neither attacking nor defending the rule, I'm just pointing out it exists. Below, here's what chatGPT has to say about it:
The “inadvertent whistle / dead-ball” exception on the Charbonnet 2-point try is basically a replay fairness patch.
Why the exception was created
Before the change, if an official blew the play dead (e.g., ruled “incomplete pass”) and replay later showed it was actually a backward pass / fumble, the defense (or offense) could be robbed of a clear recovery simply because everyone stopped when they heard the whistle.
That exact problem blew up in Chargers–Broncos (Week 2, 2008): Ed Hochuli ruled Jay Cutler’s fumble an incomplete pass and whistled it dead; replay showed it was a fumble, but (at the time) the Chargers still couldn’t be awarded the recovery because the whistle had killed the play. It became notorious enough that the league revisited the rule the following offseason.
So the league built in the concept of awarding a recovery if it happens in “immediate continuing action” after a play was wrongly ruled dead.
What the rule actually says (the key language)
In the replay rules/casebook, when an “incomplete” ruling is changed to a loose ball (fumble/backward pass), the ball can be awarded to the team that clearly recovered it in the immediate continuing action.
And yes, it explicitly contemplates this even in edge contexts like a Try (extra point / 2-point attempt).
That’s why the whistle didn’t automatically kill Seattle’s chance on the Charbonnet play: replay treated the whistle as part of an incorrect dead-ball ruling and then asked, “Was there a clear recovery in immediate continuing action?”
Has it been frequently invoked?
Not frequently in a “fans notice it” way. It’s invoked mainly in a pretty narrow replay scenario:
- on-field ruling makes it dead (often “incomplete”)
- replay changes it to a loose ball
- there’s a clear recovery essentially right away (“immediate continuing action”)
Rules analysts and officiating outlets described the Seahawks/Rams try as a rare example of this kind of replay ruling showing up in such a high-leverage moment.
