Couple of things -
1. Take Binoculars with you so you dont have to raise your scope to see - what if it was a person.
2. Tree looks like it was hit by a car or 4 wheeler not a deer - there are no rub markings below or above the main area, usually you will get the g2 or g3 making its own markhigher up the tree and that little limb is attached above the "rub" if a big deer was on that tree that branch would be gone.

Sorry
