I noticed a handful of times that players not on the field were noted in the play by play as "injured on the play".

I.e my offense was on the field and a defensive player was noted as injured on the play. I did the best I could to zoom in and check the numbers and am pretty sure the player was not on the field. On another occurrence, two players were injured who were not on the field. (must have been rough housing on the sidelines).

Anyone else see this?

Yes. I've posted a couple examples of this. No response yet.

Laffing..see,I been saying it for ages..."OK,Dez Bryant put your G**D*** helmet on before someone knocks you intelligent!!!!!!!!!!!!!!!!!!!!!!!!"

I haven't had a chance to investigate this yet, but I do know that injuries cannot happen if a player is not on the field- most likely it is a message that was in the queue that for some reason got applied to a play later than it happened on.

In the championship game in MFN-15 a couple of seasons back, My QB Samuel Zimmer was listed in the play by play as injured on a play where the other team scored a touchdown against my defense.

Thankfully, I looked at his player card and all categories of health were 100% and it did not affect his game play.

He must have lost his cool and punched the metal bench!

At least he didn't concuss himself by headbutting a wall: https://www.youtube.com/watch?v=MdWK-aam0Jo

Or, we have Johnny Football (who?) preparing to do a commercial for the durability of the Microsoft Surface Pro.
