Upper and lower front grill removal

Is there a way of removing the front upper and lower grill inserts without removing the whole bumper cover?

I hit a racoon at 75mph and am trying to repair the damage. Took out the lower air deflectors, cracked one of the led running lights and somehow busted a sensor loose behind the grilles. The sensor is laying on the bottom of the bumper cover now and I need to put it back where it goes.

Anyone know what this sensor could be? It would be mounted somewhere in front of the radiator.
