I re-watched the game last night. The initial ruling on the field announcement was that the runner was down and the penalty was on return team 32. It was a clearly a fumble on the play. But then the penalty was changed to kicking team 43. Not sure how you go from 32 to 43. But the replay clearly shows it was the right call. Right before Miami went to re-punt they stopped for another review. That may have been to make sure they had ball marked correctly.
The second stoppage was yes to make sure the enforcement was correct and to confirm to Martin because it was announced improperly on the field.
The fumble can be easy to lose on a play like that, because you don’t have it all boxed in and you can get blocked out just to the nature of the play. That’s why we have replay, and there it worked. As for the foul announcement, having a post kick foul like that on the kicking team is very rare and probably caught them off guard. Again, fixable and was fixed.
